Abstract:
In recent years quite a number of important coast protection and harbour construction works in Europe, in the U.S.A. and in Japan have been built or strengthened with the use of asphalt according to established methods of construction in various countries. These works have proved to be not only technically sound and durable but also economical in initial capital investment as well as in maintenance costs. Moreover, as the results obtained have been very encouraging, new outlets and methods of construction with asphalt are being sought, and systematically investigated and developed to cover a wider field of application for coast protection and harbour construction works. Although there are many purposes and means of applying asphalt constructions for these works, the author has limited the scope of his paper to describe in particular the fundamental problems related to the hydraulic and asphalt-technical aspects of building dams and dikes of sand according to the hydraulic fill process, covered and protected by a two course hot-mix asphalt revetment or layer. Assuming a general knowledge of the various facets of hydraulic dam and dike constructions and of asphalt construction methods the author deals with essential items concerning the hydraulic and strength design of asphalt revetments for dikes and dams and describes certain details of construction that require particular attention and perhaps further investigation as experience has proved.

Abstract:
The aim of the study was to determine the geotechnical characteristics of the unburnt colliery spoils after coal-recovery from the dumping site of one of the mines of the Upper Silesian Coal Basin in Poland. Due to grain-size distribution of tested spoils their geotechnical properties were determined using medium-sized apparatuses. In order to verify the suitability of the studied spoils for the construction of hydraulic embankments, the seepage and stability calculations were conducted for models of hydraulic embankments including the effect of flood wave passage on stress conditions within the construction and their slope stability. The test results revealed, that the studied colliery spoils are characterized by favourable values of geotechnical parameters and they fulfil the requirements for soil materials used in the analysed type of constructions. The spoils are characterized by good compactibility, relatively low water permeability and average susceptibility to mechanical disintegration, which in the case of using this material for the construction of hydraulic embankments and using proper compaction technology, should reduce their susceptibility to weathering. The results of seepage and slope stability calculations for hydraulic embankments built of the studied spoils confirmed their suitability for that type of constructions, retaining the proper inclination of slopes, whereas the variant of embankment without sealing is safer from the stability viewpoint.

Full text
Abstract:
Due to a recent increase in environmental awareness regarding fish passage through hydraulic constructions including culverts, an evaluation for the passage of wild brown trout through a weir-baffled prototype-scale culvert was performed under a variety of culvert slopes and discharge conditions. The influence of the sample fish population and the length of the individual fish on passage rates were investigated; the data showed that the brown trout fish passage sample size evaluated in this study (25 per test) was sufficiently large to minimize sample size dependency. Fish behavior while traversing the culvert was observed and reported, including resting/staging zone locations. Turbulent flow through weir baffled-culvert was also simulated numerically using three-dimensional numerical model employing the (k- �) model, Renormalized Group k-� model (RNG), and Large Eddy Simulation (LES) model. Experimental data measured with the Particle Image Velocimetry (PIV) were used to assess the accuracy and the applicability of these turbulence models in predicting the turbulent flow characteristics of the flow through a weir-baffled culvert at different spatial locations inside the culvert for variety of culvert slopes and flow rates. The influence of flow rates and culvert slopes on the forward velocities and reverse velocities was evaluated. It was noted that the influence of the flow rates on the flow velocities depends on the culvert slopes. Turbulent kinetic energy and flow direction effects on flow characteristic were also evaluated. Validation of Manning’s equation and Manning’s roughness coefficient for the tested culvert were reported.

Abstract:
At Uddeholm AB, they today use two overhead cranes with chains to move and tilt steel sheets for visual inspection of surface defects. The tilting is done to give the operator a better view of these defects using reflection of light. The problem with this approach is that it is combined with danger of life with hanging load, in case a chain breaks. Therefore Uddeholm AB would like to develop a tilt table that can be mounted on their lift table they use today. To solve this problem, 5 concepts was developed using a product development process. The chosen concept was further developed into a product that met the defined load case to tilt the sheets, weighing up to 20 tonnes, 55 degrees. The design that was selected use two points of rotation and is driven by three hydraulic cylinders. The structure has been calculated by hand and with the structural mechanics software Ansys. To tilt the table a complete hydraulic system was developed and dimensioned. The hydraulic system has been calculated by hand and simulated by a computer program called Hopsan developed at Linköping University.
På Uddeholm AB använder man idag två traverser med kedjor för att flytta och tilta stålplåtar för syning av ytdefekter. Tiltningen sker för att operatören lättare ska kunna se dessa defekter med hjälp av ljusreflektioner. Problemet med detta arbetssätt är att det är förenat med fara för liv med hängade last då en kedja skulle kunna gå av. Därför vill Uddeholm AB ha hjälp att utveckla ett tiltbord som kan monteras på deras lyftbord som används idag. I detta arbete togs det fram 5 koncept med hjälp av en produktutvecklingsprocess för att lösa problemet. Ett koncept valdes som utvecklades till en produkt som klarar det definierade lastfallet att tilta plåtar som väger upp till 20 ton 55 grader. Den valda designen som valdes använder två rotationspunkter och drivs av 3 hydraulcylindrar. Konstruktionen beräknades för hand och med strukturmekanikprogrammet Ansys. För att driva konstruktionen utvecklades och dimensionerades även ett komplett hydraulsystem. Hydraulsystemet har beräknats för hand och simulerats av ett datorprogram som kallas för Hopsan som utvecklats vid Linköpings universitet.

Edwards, Andrew J. "Properties of hydraulic and non-hydraulic limes for use in construction." Thesis, Edinburgh Napier University, 2005. http://researchrepository.napier.ac.uk/Output/6884.

Full text
Abstract:
The term "lime" comes from the word limestone. Limestone rocks were converted to lime powder by burning (calcining). The process of converting limestone to lime was an old process and it has been well documented, archaeologically. It has been established that the production of lime is the oldest industrial process can"ied out by humankind, dating back thousands of years. In fact, 3650 years ago Moses instructed the people of Israel, after they crossed the Jordan River, to set up large stones and whitewash them with lime and write the laws of God in lime. Lime was the most commonly used cementatious binder until about a century ago, when its use started to decline. It was replaced by Portland cement, a material essentially developed for structural purposes in the era of the industrial revolution. Portland cement has certain advantages over lime. The material develops strength and hardens faster for work to be carried out at a greater pace with better quality control and agreed standards. It has now become the dominant cementitious binder, part of it due to aggressive marketing of the material by the manufacturers. The use of Portland cement in the restoration and conservation of old buildings and structures in the UK over the past few years has resulted in a series of problems and cost millions of Pounds to eradicate. The decline in the use of lime in many countries has not only caused a diminution of its production, but has also contributed to a gradual disappearance of the traditional skills required both to produce a high quality product and to use it in construction. Therefore it is necessary to reintroduce and revive the old tradition of using lime by providing more information about its production and use. At present there are no comprehensive standards or code of practices, British or European to aid engineers and contractors in the use of hydraulic and non hydraulic limes in construction. BS EN 459 (2001) gives guidance on the chemical and physical properties of limes but it does not provide vital information about lime-based mortars e.g. mix proportions, mixing process, bond with masonry units, curing methods and all other necessary aspects to assess in the use of the material in construction. At present it is very easy for engineers, contractors and consultants to misuse lime mortars in new construction or in restoration and conservation of old buildings. Part of the decline in production of lime and reluctance of use in construction is due to the lack of understanding of the material properties and its performance in structures. Therefore it is necessary to examine and revive the old tradition in using lime mortars in construction and look at the new technologies used presently in the production process in order to provide the necessary background and information to aid the use of the material The present study provides a literature review, test results, discussions, conclusions and background information to set up standards in the production and use of hydraulic and non-hydraulic limes and their mortars in the construction of new buildings and the restoration and conservation of old buildings. Hydraulic and non-hydraulic limes have an excellent track record in buildings through history but their use in the UK was missed for some thirty years or more. Part of the reason for undertaking this research programme was to examine the properties of pre-packaged hydraulic limes available in the market at present. The properties of limes vary considerably dependent on the raw materials, composition and manufacturing process. The results of this study showed that there was a great variation in the properties and performance of limes and their mortars. The results also showed that the properties of lime mortar improved by adding different percentages of POliland cement. The research examined the effect of sand grading on the lime mortars compreSSIve, splitting and brick/mortar bond strength. The thesis also investigated the effects of using different casting moulds and curing methods on mortar strength. The results showed that the porosity of lime mortar was one of the reasons it was a success in the past and why it was so important nowadays to use it in the restoration and conservation of historic buildings.

This paper discusses the potential of centralized or decentralized electro-hydraulic (EH)-drives in comparison to conventional hydraulic systems. The systems are presented in diagrams covering the major electric and hydraulic components for an exemplary application, but also include specific technical data like the sizing of the components according to power, pressure, rotational speeds etc. In a second step, all systems are compared and evaluated based on criteria like design effort, energy saving potential, controllability, and servicing and maintenance of the machine. The resulting effects on fuel consumption are summarized as well. Finally, an evaluation of the potential of EH-drives in construction machinery and a derivation of the demands for future customization of electro-hydraulic linear drives is given on the basis of a SWOT-analysis from the point of view of a construction machinery OEM.

Abstract:
Évaluer la durabilité des digues fluviales en terre, correspond à estimer la durée d’usage d'un ouvrage dans son environnement. Nous avons tenté de répondre à deux questions scientifiques alimentant cette réflexion, qui sont : (1) caractériser l’effet de l’environnement météorologique sur les digues et (2) caractériser ses conséquences sur la performance en perméabilité. La première partie du travail réalisé a confirmé l’existence d’un zonage au sein des ouvrages en terre. Le zonage résulte des interactions des sols avec l’atmosphère et la météorologie du site. Sa description a été basée sur l’analyse d’un ouvrage en terre instrumenté situé à Héricourt (Haute-Saône) près de Belfort, et a été confirmée par l’analyse géotechnique d’une digue ancienne située à La Ville-aux-Dames (Indre-et-Loire) près de Tours. La météorologie des sites, alternant période sèche et humide, influence le comportement des talus, des plateformes et du cœur des digues, avec des intensités et des conséquences variables sur leurs performances. Une digue dans le Sud de la France vieillira différemment d’une digue dans le Nord. Une carte de localisation des secteurs d’égales sollicitations hydriques sur un ouvrage en terre, est proposée à partir des indicateurs de Thornthwaite. La deuxième partie a étudié plus finement l’effet des cycles hydriques sur des matériaux de digues compactés. Des échantillons observés au tomographe à Rayon X et en porosimétrie mercure, ont montré l’importance de ces cycles sur la microstructure. La caractérisation menée en parallèle par la mesure de la perméabilité sur des échantillons ayant subi le même nombre de cycles, montre que la performance se dégrade progressivement. Ces observations couplées ont été traduite en courbes de dégradation valables pour des matériaux compactés en talus de digue : elles traduisent l’idée d’un décompactage progressif des matériaux sous l’effet des cycles hydriques caractéristiques de la météorologie des sites. Ces mesures de perméabilité ont été utilisées pour simuler le vieillissement d’une portion de digue à La Ville-aux-Dames grâce à des calculs numériques réalisés avec Géostudio (Slope/W et Seep/W). Des recommandations concrètes en matière de gestion des digues à partir des concepts de durabilité sont proposées. La méthode déclinée intègre des éléments issus de ce travail
The durability of earthen river levees is assessed by estimating the time a structure will be able to protect against flooding events in a specific environment. We have tried in this work to answer two scientific questions: (1) which are the effects of the meteorological environment on the dikes and (2) what are the consequences on hydraulic conductivity performance ? The first part of the work confirmed the existence of specific zoning in the earthworks through monitoring. Zoning results from soil interactions with the atmosphere and meteorology of the site. Its description has been based on the analysis of an instrumented earth structure located in Héricourt (Haute-Saône) near Belfort, and confirmed by the geotechnical analysis of an old dike located in La Ville-aux-Dames (Indre-et-Loire) near Tours. The meteorology of the sites, alternating dry and wet periods, influences the behavior of the slopes, the platform and the core of the levee. In each zone, the intensity of the meteorological effects varies and influences their performance. Different marks of deterioration will appear in a levee in the South of France than in the North. A map of the geographic location of equal water stress for earthen structure in France, is proposed, based on Thornthwaite indicators. The second part examined more closely the effect of water cycles on compacted soils extract from the La Ville-aux-Dames levee. Samples observed on X-ray tomography and mercury porosimetry, showed the importance of these cycles on the microstructure. In the same time, measurements of hydraulic conductivity on samples having undergone the same number of cycles, showed that performance is gradually deteriorating. These coupled observations have been translated into degradation curves for compacted materials on earthen slopes : they reflect the idea of a progressive decompaction of the materials under water cycles effect, which are a characteristic of site meteorology. The laboratory results were used to simulate the aging of a portion of La Ville-aux-Dames using Geostudio (Slope/W and Seep/W) numerical calculations. Recommendations for levees management, based on sustainability concepts are proposed at the end of this work. They declined methods and new axes for applied researches

Abstract:
Some relevant aspects of dynamics and control of heavy-duty hydraulic machines in a teleoperated mode were investigated. These machines, such as excavators and forest harvesters, are mostly used in primary industries. They have a manipulator-like structure with a nonlinear and coupled actuating system. The aim of the project is to investigate different approaches towards converting such machines, with minimum changes, into task-oriented human-supervisory control systems. This provides the opportunity to use both human supervision and robotic power in hazardous environments and for tasks for which human decision is necessary. A methodology was developed for fast and accurate simulations. Analytical, steady-state and numerical techniques were combined using Large-Scale Systems analysis. The inclusion of nonlinearities in the form of discontinuities (e.g., gear backlash and stick-slip friction) in the model was investigated. Numerical simplifications of the structural dynamics and alternative solutions for the hydraulic part were also studied. The model describing the performance of the machine has been written in ACSL (Advanced Continuous Simulation Language) on a VAX computer system. A modified version of the program is at present running close to real-time on a single processor in conjunction with high speed graphics in a manner similar to a flight simulator used for human interface studies and training. The model also evaluates the performance of the machine in a teleoperated mode and under different control strategies. As a result a velocity control algorithm has been developed which is applied in conjunction with the closed-loop components for teleoperation of heavy-duty hydraulic machines; it is basically a feedforward compensation which uses the measured hydraulic line pressures along with fluid-flow equations as criteria to control the joint velocities as well as to uncouple the interconnected actuating system. The control algorithm has been written in C language and is running on an IRONICS computer system, interfaced between the human operator and the machine. The simulation results are supported by the experimental evidence. The experiments were performed on a Caterpillar 215B excavator. Improved operator safety, extension of human capability, job quality and productivity increase are the advantages of a successful implementation of robotic technology to these industrial machines.

Abstract:
In this thesis we investigate the problem of automatic calibration and control of hydraulic components in the domain of construction equipment. Methods that are able to remove a costly manual approach in favour of an automatic one are investigated and evaluated. The thesis aims to investigate what methods are available in achieving this goal as well as evaluate the performance and applicability of such methods in the domain of construction equipment. The literature indicates that a great focus is put on learning a model of the plant at run time in order to provide accurate control. Common approaches to the problem are the Recursive Least Square method and PID controllers for non-linear systems, but other methods are also present, such as the Nodal Link Perceptron Network (NLPN). The methods chosen to be compared are the existing method of manually calibrating two set points for start and end current and interpolating between them; the use of a PI controller with a static line inverse model; a PI controller with a static curve inverse model; a PI controller with an NLPN adaptive inverse model and lastly, a completely NLPN based control strategy. The methods were implemented in Matlab Simulink and evaluated in simulations based on data collected from real wheel loaders in the construction equipment domain, produced by Volvo CE. The simulations are performed on data from three machines and were evaluated twice for the adaptive methods in order to evaluate how well the methods improved. The results were then evaluated in terms of average absolute error, as well as a discussion of the behaviour shown in the plots. The evaluations indicate that the most effective method for control is the PI controller using a static line inverse model. The method produces the smallest average error of both actions evaluated, lifting and lowering of the boom, while the complete NLPN solution provide the worst results.

Abstract:
The surfaces of building materials of hydrotechnical constructions undergo the process of algae biofouling. The degree of damage depends on the environmental factors that are affect-ed by the level of anthropogenic load areas. Modeling the biofouling process of concrete with algae under laboratory conditions has allowed determining their impact on the building ma-terial, accompanied by changes in chemical and mineralogical composition of the surface of products. The microscopic examination of sample’s surfaces and evaluation of the effective-ness of various ions leaching from building materials shows the results of "algal attack" relat-ed to the acceleration of biodegradation of materials under the influence of aggressive meta-bolic products, mechanical action neoplasms, creating optimal conditions for the development of subsequent aerobic microbial decomposers. To clarify the nature of chemical processes in the system “algocenosis – concrete” the changes of chemical and phase (mineralogical) com-position of the surface layer of concrete sample were studied. The effect that algae produce on hydraulic engineering constructions is due to the fact that these organisms, belonging to phototrophs and standing at the beginning of the food chain, initiate new microbial growth.

Abstract:
The target application of this study is hydraulic excavators, which are one of the most common machines found at construction sites across the world. Road constructions and improvements, laying operation of cables or pipes and building can be seen in urban areas and digging and dumping operations of natural resource are done in country regions. For the construction site in urban areas, mini hydraulic excavators with operating weights up to 6 tons are often used and they make up more than 60% of the total hydraulic excavators market [1]. In recent years, a number of new system architectures for mobile hydraulic systems have been proposed. Examples of such improved architectures are displacement control, transformer systems and valve controlled systems with multiple pressure rails. For these systems, electronic controls are always used. Although these new methods are promising, they cannot be applied to mini-excavators, because today’s mini-hydraulic excavators do not use electronic controls as this would increase costs and make the system complex. Therefore, the goal of this study is to propose a fully hydro-mechanical valve controlled constant pressure system, which can be applied to mini-excavators in the future. This paper begins by introducing the details of this novel hydraulic system and shows its advantages. Using a simulation model of an 18 ton excavator, it is confirmed that the novel system functions well and the energy efficiency is compared to a conventional Load Sensing system. The simulation results show that the novel system can save 22% and 24% of fuel in leveling and 90° dig-dump cycles respectively.

Abstract:
East coast is the most storm part of the Black Sea because extent of the water area of the Black Sea more than 800 km. In a year there are about 17 days strong storm. Almost rectilinear outlines of the coast on a site from the river Tuapse to river Psou testify to destructive force of storm at low durability of the rocks composing the coast. The wave mode in the high sea can be determined by standard fields of a wind which build with use of weather maps. For a basis of typification take the direction and gradation of speed of a wind for that part of the water area within which it is required to define elements of waves. The main lack of a method is a short row – 10 years therefore the forecast for 25, 50 and 100 years on this row is estimated. Besides, for the district of Sochi the considerable share of excitements of a ripple (50–75 %) which are formed in different areas of the sea is characteristic. Therefore for this region any settlement method for wind excitement in the high sea won't reflect the actual mode of excitement and parameters of waves at the coast. Therefore in this case it is necessary to use all available actual data on excitement at probably bigger depth of supervision and all data on impact of the maximum storm on the coast in similar to the area of research conditions. The most qualitative for the considered coast are materials of supervision in Pitsunda. For application of these data for other sites of the coast taking into account a refraction recalculation of these supervision from shallow water is made for excitement of the deep sea. These data can be used for calculation of elements of waves on the Sochi coast. For the accounting of features of a wave mode at construction of such responsible and expensive constructions as ports, creation of new wave posts for long-term supervision is necessary. Especially it is actual in the Adler district of the city of Sochi where parameters of extreme storm are estimated generally on the put damage, instead of on series of observations over excitement. Tool supervision over excitement were carried out on northern to a pier of the Sochi port after the completion of its construction and allowed to define instrumentalno wave loads of a hydraulic engineering construction during a storm. Again created constructions of Mzymta seaport on the coast of the Imeretinsky bay and created during reconstruction of the Sochi seaport a new northern pier could form base for the organization of tool supervision over excitement on rather big depths near 15–20 M that it is quite enough for supervision of the maximum waves to their collapse.

Abstract:
The lightweight constructions and components stiffness play an important role in mechanics and in particular in high performance robots. In this paper the Virtual Prototyping Design (VPD) approach for addressing the robot design to this goal is shown. The VPD is applied to three mechanical problems of Walking Hydraulic Robots (WHRs): the first one deals with the leg joint sensitivity analysis; the second one concerns a force sensor optimization while the third one presents the torso structural verification. In all the aforementioned studies the experimental tests and the fitting analyses for model validation were carried out reaching satisfactory results.

Abstract:
Below is a brief overview of several quantitative methods for selecting the locations of hydraulic engineering constructions (HEC) to minimize the related environmental costs. These methods were developed and tested by Eco-Express-Service, a company with over twenty years of experience in the industry and extensive expertise in designing HECs. We conduct the following: 1) A multidimensional cluster analysis of the expected human impact; 2) An assessment of the ecological-economic risk in the form of the expected value of the predicted harm to the environment; 3) An express estimation of the expected “environmental cost” of construction activities. Each of these methods is justified, described and illustrated by a specific example. Their use allows to solve such important practical tasks as quantification, classification and the quantitative comparative assessment of the expected impact on the marine environment. This becomes especially important when choosing the optimal location for an HEC and implementing environmental safety measures. An important point is that all of these methods can be recommended for use as Marine Spatial Planning (MSP) “instruments”.

Abstract:
Large dams, as well as conventional hydrotechnical constructions with the role of breaking the drainage slope (waterfalls or bottom sills), flood mitigation or with the role of protection against floods (shore defences) have a profound impact on the environment. Due to these constructions, the ecosystems on the Bistrița Ardeleană river have undergone changes or even established new ones. This paper wants to highlight the morphological changes of the Bistriţa riverbed by analysing the transversal profiles made between 1972 and 2015. The profiles were made in the flow measurement section at two hydrometric stations, one being located in the upstream part of the river basin and the other before the Bistrița river flows into the Șieu river. By comparing the results obtained from the profiles made before the Colibița hydrotechnical system was started or completed with the data obtained from the profiles after the commissioning of the Colibița hydropower plant, we managed to highlight that the Bistrița Ardeleană riverbed registered several negative effects in terms of morphologically both vertically and horizontally. We also found that the riverbed downstream of the dam there is a phenomenon called hydraulic paving.

Abstract:
Steel tube umbilical designs are becoming more complex and are being deployed in increasingly severe environments. Umbilical designs can now accommodate up to 3-inch diameter steel tubes for chemical and hydraulic injection, up to four layers of armoring, multiple electrical cables and fiber optic lines. Large power transmission cables are also being incorporated in umbilical constructions. This is leading to ever increasing umbilical mass, radial loads, pressure loads and increased demands on the designer to demonstrate adequate fatigue capacity. A method has been developed for predicting the fatigue response of deepwater umbilicals, particularly for umbilicals subject to high tension and bending loads. The method involves predicting cyclic stress in the umbilical components (steel tubes or power cables) using an industry standard, general purpose numerical tool. It comprehensively accounts for the complex relationships between umbilical curvature, tension, inter-layer contact forces and tube stress variation. This paper describes the validation of the method against measured data obtained from full scale fatigue tests performed on two deepwater umbilicals. A key feature of the method relates to the construction and verification of suitable finite element (FE) models and the simulation of fatigue conditions. For the validation of the models, results from the full scale dynamic umbilical test cases incorporating bend stiffeners and loading arms are used, which demonstrate umbilical hysteretic behavior under cyclic bending loads. Hysteretic stress-curvature loops obtained from strain gauge readings for various tube locations within the bend stiffener regions for two umbilical constructions with significantly different lay-up configurations and fatigue stress regimes are used for comparison to strain predictions from the FE models. A significant advantage of the modelling and analysis methods described in this paper is that it employs the widely-used industry standard numerical FE tool, Abaqus, for the modelling and analysis of the umbilical. Key features and insights from the modelling, analysis approach and validation against the results of a deepwater umbilical dynamic test program are described. A robust and efficient method for the independent assessment of the fatigue capacity of deepwater umbilicals is demonstrated.

Abstract:
The US Army Corps of Engineers, St. Paul District, and its non-federal sponsors are designing and constructing a flood risk management project that will reduce the risk of flooding in the Fargo-Moorhead metropolitan area. There is a 30-mile long diversion channel around the west side of the city of Fargo, as well as a staging area that will be formed upstream of a 20-mile long dam (referred to as the Southern Embankment) that collectively includes an earthen embankment with three gated structures: the Diversion Inlet Structure, the Wild Rice River Structure, and the Red River Structure (RRS). A physical model has been constructed and analyzed to assess the hydraulic conditions near and at the RRS for verification of the structure’s flow capacity as well as optimization of design features for the structure. This report describes the modeling techniques and instrumentation used in the investigation and details the evaluation of the forces exerted on the proposed bulkheads during emergency operations for the RRS.
