Abstract:

There is a growing interest in the application of submerged rubble mound breakwaters as coastal defence structures. As their defensive ability highly depends on the amount of wave energy remaining at their lee side, the accurate prediction of the energy in the lee of such structures is of utmost importance. Past experiments have shown that the behaviour of rough permeable rubble mound structures under oblique wave attack was found to be significantly different from that of smooth impermeable low crested structures. This behavioural difference has led to the research objective of this present study which is to investigate oblique wave transmission by rough impermeable rubble mound submerged breakwaters using 3D physical model tests. This study intentionally uncouples two parameters, being the permeability of the core and the roughness of the breakwater. Analysing the data of this study shows that the permeability of the core has no visible influence on the structure's behaviour with respect to the influence of oblique wave attack. The fully permeable rough rubble mound breakwater behaves analogous to the fully impermeable rough rubble mound breakwater.

Abstract:

At the 19th ICE Conference in Houston in 1984 an alternative concept for the design of rubble mound breakwaters was introduced. This concept has the objective of providing a least cost structure by optimizing the use of locally available materials and utilizing simple construction procedures. Contractors' bids demonstrated that significant cost savings could be achieved, when compared to the cost of traditional designs. Considerable prototype experience has now been obtained with this concept of breakwaters. Breakwaters have been built using the concept in Canada, the United States, and Iceland since 1984 and have been subjected to storms and ice action. Prototype observations have supported the performance predicted during the design process. In this paper surveys of a breakwater taken after construction and after storm action are presented. In addition to wave action, this breakwater has also been subjected to extensive ice action. The response of the breakwater has been monitored and observed and is discussed.

Abstract:

Oscillating water column (OWC) wave energy converters can be integrated in harbor protection structures, such as vertical, rubble mound and piled breakwaters. The interaction between the incident wave and the structure, in which the OWC device is integrated, is significantly different, since the structure of the vertical breakwater is impermeable, while that of the rubble mound breakwater is porous. The performance of the OWC device for the three configurations is analyzed for a range of wave periods from 6 to 12 s and a wave height of 1 m. The OWC device integrated into the vertical breakwater shows the best performance (maximum mean pneumatic power of 70 kW), and the mean pneumatic power is globally 3 % higher than that of the OWC device integrated into the rubble mound breakwater (maximum mean pneumatic power of 67.4 kW). The performance of the OWC device integrated into the piled breakwater shows a similar trend to the OWC device integrated into the vertical breakwater for wave periods lower than 9 s, but it has a significant loss of performance for higher wave periods.

Abstract:

The object of this present research is to study probabilistic design of armor blocks protecting composite breakwaters and to produce optimum design methodology for S-shaped breakwaters in terms of failure probability and construction cost. Failure probability in the vicinity of the still water level is greatest in the case of uniform sloped breakwaters. Therefore,S-shaped breakwaters of which the slope near the still water level is milder have a reduced risk of damage compared to uniform sloped ones. The optimum design index presents good economics and reliability in rubble-mound breakwater design.

Abstract:

In order to create calm ocean water, breakwater is essential for reducing wave energy. Rubble-mound breakwater with tetrapod and dolosse armor can be a solution in reducing ocean wave energy. This research aims to understand the effectiveness of rubble-mound tetrapod and dolosse breakwater in reducing wave energy with sea level condition variation in a laboratory. The method of this research is an experimental method that uses a breakwater physical model with various scenarios. Testing scenarios are determined based on water depth, wave period (T), and armour structure. The results of this research showed that rubble-mound tetrapod breakwater is the most effective breakwater with an average reducing percentage of 86.7%. Rubble- mound tetrapod and dolosse breakwater physical model have high effectiveness because they are built by rubble mound structure that forms a sloping side. These structures are effective in reducing wave energy because the waves get in between rock slits. So, the wave energy reduces when it passes through the breakwater. This research can give some information and analysis in planning a breakwater effectively and efficiently in the ocean.Keywords: breakwater physical model, tetrapod, dolosse, wave energy

Abstract:

As the name implies, a breakwater is a barrier constructed to break up and disperse heavy seas, to shield the interior waters of a harbor from winds and waves, and to provide shelter and protection for ships, shipping facilities, and other harbor improvements. Breakwaters are structures used to improve a naturally protected (sheltered) harbor or to create a sheltered harbor at locations required for shipping, refuge, recreation, etc. Breakwaters may be roughly divided into two main groups, the vertical-wall type and the rubble-mound type. A possible third group, the composite type, consists of the wall-type placed upon a rubble-mound foundation. Since the experience of the San Francisco District, Corps of Engineers, has been limited to the construction of rubble-mound breakwaters and jetties in as much as practically all breakwaters on the Pacific Coast are of rubble-mound construction, the second half of this paper has been limited to the consideration of this type of structure. The first half of the paper discusses general subjects (choice of location and type of breakwater, etc.) relevant to both types. Until recently, the design and construction of breakwaters was largely an empirical "art" based mainly on the designer's observations of the performance of previously constructed breakwaters. Great latitude was given personal discretion and judgment, since those factors which might influence or standardize design were little understood.

Abstract:

Due to the increase of ship sizes in recent decades a number of harbours and terminals have been built in deeper waters. Accordingly, the structures which have to provide protection against wave action become higher, too. In most cases, these protective structures are of the rubble mound type. Under such conditions the flow induced by waves within the breakwater and the related geotechnical behaviour of the rubble mound fill become more significant fcr the overall stability and should be considered in the design. In addition, it is known that the scales usually adopted in hydraulic models (1:30 to 1:60) for investigating the stability of large rubble mound breakwaters generally lead to scale effects with respect to the flow field inside the breakwater. This means that small-scale model tests are not appropriate for investigating the internal flow patterns or for evaluating the pore pressure field induced by the incident waves in,the core material. because of the uncontrolled conditions in the prototype, and since the actual permeability of the prototype rubble mound fill cannot be predicted (segregation, settlement, variation in grading, etc.), the use of large-scale physical models seems to be the most promising method for basic investigations of this kind. Moreover, the results of such largescale model tests may be used to validate the usual smaller scale models and to calibrate numerical models. Therefore, it is one of the objectives of our research programme on rubble mound breakwaters, which started in 1987, to concentrate on the evaluation of the wave-induced flow and pore pressure distribution within the breakwater.

Abstract:

This paper intends contributing to an economically and environmentally sustainable development of coastal infrastructures by investigating the possibility of combining together breakwaters and Wave Energy Converters (WEC). The latter change the wave energy to electricity, which may serve both the rubble mound breakwaters and seawalls related activity and the energy demand of small human communities. Wave loadings and overtopping on a seawall and rubble mound breakwater with front reservoir are discussed on the basis of physical 2-D model tests carried out at University of Southampton (UK) and Aalborg University (DK).

Abstract:

A simplified model using the lifetime distribution has been presented to estimate the Mean Residual Life (MRL) of rubble-mound breakwaters, which is not like a stochastic process model based on time-dependent history data to the cumulative damage progress of rubble-mound breakwaters. The parameters involved in the lifetime distribution can be easily estimated by using the upper and lower limits of lifetime and their likelihood that made a judgement by several experts taking account of the initial design lifetime, the past sequences of loads, and others. The simplified model presented in this paper has been applied to the rubble-mound breakwater with TTP armor layer. Wiener Process (WP)-based stochastic model also has been applied together with Monte-Carlo Simulation (MCS) technique to the breakwater of the same condition having time-dependent cumulative damage to TTP armor layer. From the comparison of lifetime distribution obtained from each models including Mean Time To Failure (MTTF), it has found that the lifetime distributions of rubble-mound breakwater can be very satisfactorily fitted by log-normal distribution for all types of cumulative damage progresses, such as exponential, linear, and logarithmic deterioration which are feasible in the real situations. Finally, the MRL of rubble-mound breakwaters estimated by the simplified model presented in this paper have been compared with those by WP stochastic process. It can be shown that results of the presented simplified model have been identical with those of WP stochastic process until any ages in the range of MTT F regardless of the deterioration types. However, a little of differences have been seen at the ages in the neighborhood of MTTF, specially, for the linear and logarithmic deterioration of cumulative damages. For the accurate estimation of MRL of harbor structures, it may be desirable that the stochastic processes should be used to consider properly time-dependent uncertainties of damage deterioration. Nevertheless, the simplified model presented in this paper can be useful in the building of the MRL-based preventive maintenance planning for several kinds of harbor structures, because of which is not needed timedependent history data about the damage deterioration of structures as mentioned above.

Abstract:

Melby presents a formula to predict damage evolution in rubble-mound breakwaters whose armour layer is made of rock, based on the erosion measured in scale-model tests and the characteristics of the incident sea waves in such tests. However, this formula is only valid for armour layers made of rock and for the range of tested sea states. The present work aims to show how the Melby methodology can be used to establish a similar formula for the armour layer damage evolution in a rubble-mound breakwater where tetrapods are employed. For that, a long-duration test series is conducted with a 1:50 scale model of the quay section of the Ericeira Harbour breakwater. The eroded volume of the armour layer was measured using a Kinect position sensor. The damage parameter values measured in the experiments are lower than those predicted by the formulation for rock armour layers. New and coefficients for the Melby formula for the tested armour layer were established based on the minimum root mean square error between the measured and the predicted damage. This work shows also that it is possible to assess the damage evolution in scale-model tests with rubble-mound breakwaters by computing the eroded volume and subsequently, the dimensionless damage parameter based on the equivalent removed armour units.

Abstract:

This thesis presents an original theoretical investigation, based on diffraction theory (extended for permeable structures by Sollitt & Cross [56]), of the performance of segmented rubble mound breakwaters. The amount of protection offered by such a breakwater is a function of the rubble construction (characterized by porosity and permeability), geometry and spacing of segments as well as depending on the the characteristics of the incident wave field. To explore the influence of these factors on the performance of these breakwaters, the diffraction by three related structures have been considered :a periodic array of impermeable blocks, a single continuous rectangular section permeable structure and a periodic array of permeable blocks in shallow water.

Abstract:

Black Sea coast line is a hazardous region especially in winter due to the dominant wave action. Therefore, rubble mound breakwaters used as ship shelters are vital structures especially for the fishermen. Construction of the breakwater requires good quality durable armourstones. Due to the nature of the rubble mound breakwaters, armourstones having various sizes and types are used in the construction of these structures. The deterioration of these armourstones with time in the form of abrasion and disintegration may result in the failure of the breakwater. Therefore, it is important to investigate the durability and quality of the armourstones to be used in these structures. In this thesis, the properties of the armourstones taken from five rock quarries and used in the Hisarö
nü
(Bartin), the Tarlaagzi (Bartin) and the Alapli (Zonguldak) rubble mound breakwaters were studied both in field and laboratory in order to assess their qualities and long term durabilities. Based on the in-situ observations and laboratory tests, the Kavakdere, Kavukkavlagi and the Tarlaagzi limestones are good (durable) rocks. However, the Ç
ö
mlekç
ikuyu andesite is found to be generally marginal rock, and the Kiran sandstone is poor rock. CIRIA/CUR, RDId, RERS and Wet-Dry strength ratio classifications are in good agreement with the in-situ observations and the results of the laboratory tests. However RDIs, Average Pore Diameter and Saturation Coefficient classifications do not fully reflect the reality.

Abstract:

Today, more than forty percent of the world’s population lives within 100 kilometers of a coastal area, and population densities are only increasing. In recent years, extreme conditions have resulted in several failures of coastal protection structures around the world. During these failure events, the incurred cost of damages and loss of life has been nearly immeasurable. Rubble mound breakwaters have been used for millennia, and are critical even today for the protection of coastal areas. In the last several decades, the popularity of using concrete armour units in place of natural rock has risen greatly. However, the quantitative interaction between wave hydrodynamics and the armour layer is still not clearly understood. Due to highly complex, turbulent flow patterns that occur in the armour layer, direct assessment of forces acting on individual units has not been practical. This has prevented the coastal engineering field from applying a force-balance design approach that is commonplace in other civil engineering disciplines. Instead, a wealth of experimental testing and past case studies have resulted in a wide array of empirical formulae and design techniques. These approaches are often very idealized and do not account for all parameters that have been shown to affect armour unit stability. The current study aims to quantify the forces and pressures acting on units within an armour layer, using an experimental approach. This was achieved by developing an instrumented Core-Loc armour unit. This armour unit was outfitted with 6 pressure sensors, and the ability to be mounted on a force transducer. This unit was then put through a performance analysis and calibration procedure, before being extensively tested in a breakwater setting. Wide ranges of wave conditions were utilized, with the unit at three different locations along the breakwater slope. This was done to isolate both the effect of various sea state parameters, and the effect of unit location along a breakwater slope versus generated forces and pressures. In addition to the experimental study, an accompanying numerical study was performed in OpenFOAM. This had the intent of both developing general modeling rules of thumb for rubble mound breakwaters, and for replicating the experimental results. The results showed that using relatively low-tech, low-cost, and widely available instrumentation was capable of performing in a coastal engineering setting. The performance of the unit showed great promise for “smart-units” to usher in a new paradigm of experimental testing for rubble mound breakwaters. From the results of the performance analysis and calibration procedure, it was evident that the unit could record forces and pressures to a high degree of accuracy. From the breakwater testing program, notable relationships between unit location, surf similarity, and wave steepness emerged. It appeared that the largest hydrodynamic interaction with units occurs slightly below the SWL. As well, both decreased surf similarity, and increased wave steepness resulted in higher hydrodynamic interaction for all locations. General rules of thumb for modeling armour units, as well as wave conditions in a breakwater setting were developed for the numerical study in OpenFOAM. Additionally, the calibrated numerical model was capable of reproducing the experimental results with reasonable accuracy.

Abstract:

2012 - 2013
Le aree costiere rappresentano sistemi naturali del tutto unici, così come unici sono i fenomeni che le caratterizzano. L’erosione dei litorali, divenuta ormai un fenomeno di interesse planetario, ha spinto verso un approfondimento delle conoscenze dei processi costieri, consentendo di operare nella lotta ai suddetti fenomeni, attraverso strategie sempre più mirate e attente. Una migliore conoscenza dei processi costieri, infatti, può consentire agli ingegneri di adottare approcci più corretti nella progettazione di opere di protezione costiera. La principale fonte di supporto per l’ingegneria costiera è rappresentata dalla letteratura tecnica e scientifica relativa ad interventi già posti in essere nel passato. Strumenti di conoscenza aggiuntivi possono essere forniti da fonti di diversa natura. Uno su tutti la modellistica fisica, che rappresenta senza dubbio un importantissimo mezzo di conoscenza al servizio della progettazione del tipo di opere in parola. Tramite la modellistica fisica è possibile, ad esempio, studiare fenomeni quali la propagazione del moto ondoso nel suo percorso dal largo verso riva, l’agitazione ondosa all’interno dei porti, la stabilità delle strutture sottoposte alle azioni dinamiche del moto ondoso, così come il wave runup, l’overtopping, la riflessione e la trasmissione ad esse associati. Si tratta di fenomeni la cui conoscenza risulta di fondamentale importanza quando nasce l’esigenza di progettare un’opera di difesa costiera. E il risultato è tanto migliore, quanto più sono specifiche le conoscenze su cui viene fondato il progetto. Si consideri, ad esempio, il caso delle dighe a scogliera, il cui strato di armatura più classico è costituito da massi naturali di grandi dimensioni: laddove non ci dovesse essere sufficiente disponibilità del suddetto materiale, o laddove si sia in presenza di condizioni meteomarine particolarmente gravose, le unità di armatura in massi naturali vengono normalmente sostituite da unità in calcestruzzo, per le quali esiste ormai una gran varietà. E’ evidente che, a seconda della forma e delle dimensioni delle suddette unità, nonché del numero di strati con cui esse vengono posizionate sulla mantellata, cambia sensibilmente il comportamento idraulico della struttura. Ne consegue la necessità, in fase di progettazione, di poter disporre di parametri che siano caratteristici della tipologia di unità di armatura della mantellata che si deve realizzare. L’individuazione dei suddetti parametri deve essere necessariamente il risultato di prove sperimentali eseguite in laboratorio su modelli fisici di strutture realizzate con quelle specifiche unità di armatura. Oggetto del presente lavoro, dunque, è lo studio dei fenomeni che intervengono nell’interazione tra il moto ondoso e le strutture di difesa costiera, in particolare per un’opera a gettata costituita da una tipologia di unità di armatura in calcestruzzo non presente in mercato, attualmente sottoposta a procedura brevettuale. Il lavoro è stato condotto mediante sperimentazione su un modello fisico bidimensionale realizzato presso il Laboratorio di Ricerca e Sperimentazione per la Difesa delle Coste (LIC) del Dipartimento di Ingegneria Civile, Ambientale, del Territorio, Edile e di Chimica (DICATECh) del Politecnico di Bari. Lo studio ha permesso di individuare alcuni parametri caratteristici delmasso in oggetto, quali ad esempio il coefficiente di stabilità e il coefficiente di scabrezza, necessari per il calcolo delle grandezze con cui poter effettuare il dimensionamento dell’opera. Inoltre, sono state valutate alcune delle formulazioni presenti in letteratura per il calcolo delle suddette grandezze, al fine di analizzare la loro adattabilità al nuovo masso. [a cura dell'autore]

Abstract:

There are some empirical formulas used in the design of rubble mound breakwaters to find the weight of armour layer stone. The effect of wave grouping and spectral shape could not put into these design formulas since their effects are still under question. The influences of wave groups and spectral shape on the stability of rubble mound breakwaters have been investigated by several researchers up to now. However, results were not conclusive in these researches, where different wave grouping and spectral shape parameters were used. This study aims to investigate the influences of wave groups and spectral shape on the stability of rubble mound breakwaters by means of hydraulic model experiments. According to the result of the experiments, the damage to breakwater armour layer is almost same for different spectrum shapes and pronounced wave grouping, under the condition of similar wave statistics. Experiments also indicated that the wave trains with same significant wave height, H1/3, but with different distribution of the heights of extreme waves which were defined as wave heights higher than H1/3 in this study, cause different damage levels. Based on these results, extended experiments were conducted to observe the effect of heights of extreme waves in a wave train on the stability of rubble mound breakwaters. Results of the experiments showed that the higher the extreme waves are, the more destructive the wave train is. By carrying experimental results into design conditions, it was shown that a wave train with high extreme waves may affect the design weight of armour stone. Finally, in order to achieve more practical tools for engineering applications, occurrence probabilities of extreme waves under different spectral shapes were obtained by a numerical simulation. As a result, for different occurrence probabilities of extreme waves under the most widely used spectrums of PM and JONSWAP, necessary weight of armour stone was given in a range comparing with the formula of Meer. Moreover, it was noted that the spectral shape indirectly affects the stability not due to the wave grouping but due to the extreme waves in a wave train since the occurrence probability of the high extreme waves becomes higher as the spectral shape becomes narrower under same significant wave height condition.

Abstract:

Coastal defense structures have primary importance from obtainabilty of resources and benefits served by the coastal regions point of view. However, the construction of coastal defense structures demand a high amount of investment. Therefore, in order to reduce the risk of collapse of these structures, model studies should be carried during the design process. In this study, model investigations were carried out on Eastern Black Sea Highway Project regarding the serviceability and damage thus stability parameters. 5 different models were constructed as berm type rubble-mound breakwaters using Van Der Meer&rsquo
s approach and berm design guidelines, with a scale of 1/31.08 and they were tested both for breaking and non-breaking waves. The experiments took place in the Coastal and Harbor Engineering Laboratory of the Middle East Technical University, Civil Engineering Department. The models were constructed and tested with different berm widths and armor stone sizes forming the back armor layer in order to examine the effect of these design parameters on the stability and serviceability of the coastal defense structure to obtain the optimum alternative cross-section. Cumulative damage was minimum for the cross-section constructed with berm width 15 m assigning the width of the prototype. Water spray and run-up values were also not significant. The test results were confirming with Van Der Meer design approach.

The model aims to perform the following steps: 1. Determine the sources of uncertainties in design parameters 2. Evaluate the damage risk of coastal structures which are at design stage and are recently constructed. 3. Study the sensitivity of limit state functions to the design parameters. Different from other reliability studies on coastal projects, a new design computer program is developed that can be easily used by everyone working in coastal engineering field.

Abstract:

Ce travail de recherche a pour objectif d'étudier l'impact de la houle sur les structures de protection côtières. L'objectif principal de cette étude est d'évaluer la capacité des outils CFD à modéliser et prédire avec précision l'impact des charges extrêmes des vagues sur des digues conventionnelles en enrochement avec murs de couronnement.Pour mener cette étude, le logiciel numérique OpenFOAM est utilisé pour aborder deux questions scientifiques clés : les charges impulsives des vagues agissant sur des parapets incurvés (partie supérieure du mur de couronnement) et le développement de la houle à travers le revêtement (le milieu poreux à la base de la digue).Dans un premier temps, une houle de Stokes non-linéaire est modélisée pour évaluer les performances du solveur numérique afin de reproduire le déferlement des vagues sur un mur vertical avec un parapet incurvé, et pour évaluer les pressions d'impact associées. Les résultats calculés sont comparés aux données expérimentales provenant des essais réalisés à Hanovre (Allemagne), fournies dans le cadre du benchmark ISOPE 2022.Ensuite, la physique de l'interaction des vagues avec des digues complètement immergées est étudiée expérimentalement. Sur cette base, le présent travail examine également la capacité du solveur à simuler l'interaction fluide-structure.Enfin, le présent travail discute des avantages et des limites de ces méthodes numériques utilisées en génie côtier. Les différentes conclusions de cette étude visent à répondre à la demande de INGEROP Conseil et Ingénierie concernant l'adéquation de la CFD pour leurs applications industrielles
The present work aims to investigate the water waves impact on coastal protection structures.The primary focus of this research is to assess the ability of CFD tools to accurately model and predict the impact of extreme wave loads on conventional rubble mound breakwaters with crown walls, a structure commonly designed to mitigate wave-induced forces and fight the threats associated with sealevel rise. To carry out with this investigation, the numerical toolbox OpenFOAM is employed and the problematic is approached from two key perspectives : the impulsive wave loads acting on recurved parapets (the upper portion of breakwaters) and the wave transformation through the revetment (the porous media at the base).Initially, non-linear Stokes waves are used to evaluate the performance of the numerical solver to reproduce realistic wave breaking on a vertical wall attached with a recurved parapet, and to assess the related impact pressure records. The computed results are validated against experimental data from the large wave flume (GWK) in Hannover (Germany), provided as part of the ISOPE 2022 benchmark. Next, the physics of waves interaction with submerged crested breakwaters is investigated experimentally.In fact, the present work also investigates the capability of the solver to simulate the most relevant hydrodynamics that occurs between waves and submerged breakwaters. Finally, this work discusses the advantages and thelimitations of these numerical methods used in coastal engineering. The different findingss of this study serve to adress INGEROP's inquiry regarding the suitability of CFD for their industrial applications

Abstract:

The 2011 off the Pacific Coast of Tohoku Earthquake on the 11th of March, 2011 had induced a gigantic Tsunami and caused the catastrophic damage in the northeast coast area of Japan. Lots of breakwaters have been seriously damaged in this disaster, including the world deepest breakwaters, Kamaishi Harbor Mouth Breakwaters. According to a wave height recorder, a large hydraulic head difference between the seaside and harbor side of breakwaters was observed for long duration of several minutes or more. Such a hydraulic head difference as observed generates the seepage flow in the rubble mound underneath the caisson. The seepage flow is considered one of the influential factors causing the instability of caisson type composite breakwaters. In order to find out the instability mechanism of caisson type composite breakwaters against tsunami, 1) the pop-out phenomena of armored blocks on the mound, 2) the possibility of shear failure of rubble mound and 3) the reduction of bearing capacity of rubble mound due to seepage flow are investigated. Both theoretical analysis and laboratory experiment are represented in this paper. The safety factors for the pop-out failure and shear failure of rubble mound were theoretically derived. A scale of 1/100 model experiment was performed in laboratory. Loading tests were carried out to investigate the reduction of bearing capacity under the existence of seepage flow. From the results of laboratory experiment and theoretical analysis, it was confirmed that the pop-out phenomenon happens and the bearing capacity of rubble mound can considerably decrease due to the tsunami-induced seepage flow. It is concluded that the effect of seepage flow in the rubble mound should be taken into account when making a design of the caisson type composite breakwater against tsunami.

Abstract:

The wave-structure-seabed interaction (WSSI) around circular rubble-mound breakwater head is investigated using a three-dimensional (3D) numerical scheme. The result reveals that the presence of breakwater has strong effect on wave motion and seabed response. The turbulence induced by the breakwater head gives rise to extensive pore pressure around the breakwater head, which could further lead to liquefaction or scour and might eventually result in breakwater failure.

Abstract:

The wave-induced dynamic response and instability of the porous seabed and the rubble mound foundation under a composite caisson-type breakwater is studied using finite elements. In this study the focus is on the effect of inertial terms on the dynamic response and instability of the foundation material underneath the breakwater. It is assumed that a fully standing wave condition occurs in front of the caisson under the cyclic wave action and the dynamic response of the seabed and rubble mound is presented in terms of pore pressures and stresses induced around the breakwater. A complete formulation of the fully dynamic (FD) response requires inclusion of the inertial terms associated with both the motion of solid skeleton and that of pore fluid. However, partly dynamic (PD) and quasi-static (QS) idealizations are also possible. The objective of this study is to investigate the standing wave induced dynamic response and instability of seabed-rubble-breakwater system.

Abstract:

The breakwater is one of the most important structures in coastal areas and the rubble mound breakwaters have been most widely designed and constructed. When designing the rubble mound structures, the determination of the stable weight of concrete armor units is the most significant and critical problems. The stable weight of concrete armor units could be calculated by Hudson or van der Meer formula. The breakwater is assumed to be straight and the waves are propagating normally to the structures when using this formula. The weight of concrete armor units at the round breakwater head should be protected by 1.3∼1.6 times of that at the trunk part because the coastal engineers think it to be vulnerable. Recently the damage of concrete armor units at the convex corner of breakwater trunk was reported several times in Korea. However, there were no any design standards for this area. In this study, three-dimensional hydraulic model tests were performed to investigate the stable weight of concrete armor unit at convex corner area. The tetrapod was used to the target concrete armor unit in the study. The stable weight is suggested by stability coefficient, Kd by using Hudson formula. From this study, the stable armor weight at the convex corner is similar with that at the round breakwater head and this means that about 1.4 times of weight for trunk area was needed at convex corner area.
