Abstract:

This paper presents the design and stability analysis of Kawlewada dam (a concrete gravity dam situated in kawlewada village of gondia district) and its components. Through, the demanding years, it has been observed that failures of dams due to many factors are common. So, it is the essential to analysis the various components, parts of dam against all its modes of failures, forces acting on it, uncontrollable disasters such as earthquake, disaster, etc. For this, the preliminary data of the dam required for design, such as control levels, dimensions, crest width, base width, etc. was collected through the Inspection Engineer, posted at Dhapewada Lift Irrigation Office, Tirora, Dist. Gondia. On the basis of collected data the elementary profile and practical profile of dam was estimated, further all the major and the minor force forces acting on dam were calculated, stability analysis of designed dam against all modes of failure and for various load combinations was carried out in STAAD PRO software and was checked for permissible limits. Design of spillway, stilling basin and earthen dam was also carried out for the designed dam. Further, canal originating from the dam and carrying water to culturable command area was also designed by taking care of peak discharge as required by crops.

Abstract:

The case of a dam for an irrigation reservoir is used as an example to illustrate the different modes of failure of a water resources system. The types of failure to which a dam can be subjected are described in the first section of the paper, in terms of a framework of general reliability analysis. Two applications are considered: the case of operational failure, illustrated by means of an irrigation reservoir for arid countries, and the case of dam failure due to overtopping. Conceptual models are given which permit the inclusion of reliability and other figures of merit into both operation and safety analysis.

Abstract:

Kedung Uling earthfill dam locates at Wonogiri Regency, Central Java, Indonesia. The dam encountered sliding and settlement at the embankment wall. To minimize sliding and settlement and to optimize the dam, both field investigation and laboratory tests have been proceeded for slope stability analysis and remedial embankment wall. Soil and rock investigation around the dam, which is followed by 10 core drillings, have been conducted. Laboratory tests such as direct shear and index properties have also been carried on. The results were further used for dam slope stability model using slide 6.0 and were used to analyzed factor of safety (FS) of Kedunguling dam. 10 conditions of dam were simulated and strengthening body of dam with grouting was designed. The results showed two conditions, which are condition of maximum water level with and without earthquake at downstream, were unsatisfy Indonesia National Standard (SNI) for building and infrastructure. These conditions can be managed by using grouting for increasing stabilization of embankment wall. By setting up grouting, factor of safety increases and meet the SNI standard requirement.

Abstract:

A fitting curve of stress-strain relation given is applied in numerical analyzing based on Legendre orthogonal polynomial and least square method. The nonlinear constitutive model is employed to examine the shape of an arch dam. For the asymmetries and high water pressure, the safety of High Arch Dam is one of key issues in the design and construction of High Arch Dam. The simulation results show that the basic mechanical performance index is symmetrical distribution. The dam mainly bears pressure and no obvious tensile stress exists in the dam when water level is normal. Material yields in dam heel when 1.4 times overloading is considered. It can be concluded that the dam is reliable and the safety margin is satisfactory.

Abstract:

Uncertainty in the rainfall network can lead to mistakes in dam operation. Sudden increases in dam water levels due to rainfall uncertainty are a high disaster risk. In order to prevent these losses, it is necessary to configure an appropriate rainfall network that can effectively reflect the characteristics of the watershed. In this study, conditional entropy was used to calculate the uncertainty of the watershed using rainfall and radar data observed from 2018 to 2019 in the Goesan Dam and Hwacheon Dam watersheds. The results identified radar data suitable for the characteristics of the watershed and proposed a site for an additional rainfall gauge. It is also necessary to select the location of the additional rainfall gauged by limiting the points where smooth movement and installation, for example crossing national borders, are difficult. The proposed site emphasized accessibility and usability by leveraging road information and selecting a radar grid near the road. As a practice result, the uncertainty of precipitation in the Goesan and Hwacheon Dam watersheds could be decreased by 70.0% and 67.9%, respectively, when four and three additional gauge sites were installed without any restriction. When these were installed near to the road, with five and four additional gauge sites, the uncertainty in the Goesan Dam and Hwacheon Dam watersheds were reduced by up to 71.1%. Therefore, due to the high degree of uncertainty, it is necessary to measure precipitation. The operation of the rainfall gauge can provide a smooth site and configure an appropriate monitoring network.

Abstract:

As dams approach the end of their design life periods, retrofitting of dams is needed in many cases. For the retrofitting procedure of building a new dam close to the existing old dam without demolishing it, the interaction between the two dams and the unbounded foundation is an important issue to be investigated. The influence of the existing dam on the dynamic response of the newly built dam is examined. Two systems are analyzed, i.e., the new dam-foundation system and the dam-foundation-dam system. For the two systems, modal analysis and time history analysis using the viscous-spring artificial boundary are performed. It’s found that there’re much more vibration frequencies for the dam-foundation-dam system as compared to the new dam-foundation system within the same frequency range. The existence of the old dam also induces one more peak and a wider plateau in the response spectrum of the acceleration time history of the dam crest. However, the maximum stress distribution is not influenced much by the old dam.

A formula of sensitivity of dam strain energy to deformation modulus of foundation is derived and a relevant algorithm is proposed. The optimization of a planned arch dam indicates that, the dam strain energy and its sensitivity to foundation deformation modulus of optimal design are reduced 2.29% and 15.51%, respectively, of that of initial design, and the validity of the proposed model is demonstrated.

Abstract:

This paper combined with the adaptive principle to improve the genetic algorithms (GA) and applied it to optimal design of the shape of the concrete face rock-fill dam (CFRD). Based on the improved GA, a mathematical model was established for the design optimization of CFRD. CFRD utilizes dam cost as objective function and dam slope and geometries of the dam material partition as design variables. Dam stability, stress, displacement, and stress level are used as the main condition constraints. The calculation procedures were prepared, and the GA was used to optimize the design of Jishixia CFRD. Results show that the GA could solve the global optimal solution problem of complex optimization design, such as the high degree of nonlinearity and the recessiveness of constraint conditions, and using the GA to optimize the CFRD design can reduce the quantities of projects and engineering safety costs.

Full text

Abstract:

Existing analyses of the February 2017 Oroville Dam Crisis identify maintenance failures and engineering shortcomings as the root cause of a nearly catastrophic failure of the tallest dam in the United States. However, the focus on technical shortcomings largely overlooks the role of adaptive decision-making that eventually averted the crisis. Understanding the decisions that both created the circumstances leading up to the crisis and saved the dam from collapse requires that risk analysis be complemented by a resilience perspective. This paper presents a case study on the Oroville Dam Crisis to develop a timeline of failures and successes in the resilience processes of sensing, anticipation, adapting, and learning throughout the history of the dam. Three factors that drove poor operational and engineering decisions include: (1) misalignment of technical nomenclature and design requirements for the ungated spillway, (2) overconfidence in original engineering designs, and (3) conflicting pressure from diverse stakeholders. These factors contributed to unrealistic perceptions of dam capabilities and promoted decisions to forgo maintenance and design efforts that may have mitigated the danger.

Abstract:

Design of flood discharge becomes an important parameter in water building design planning. When analyzing the design of flood discharge, re-selection is crucial because it will determine the magnitude of the design flood discharge. Election times are adjusted to the characteristics of the Watershed (DAS). The location of the Sand Pocket plan is in Woro river, Klaten, Central Java. The unavailability of design flood discharge data at the observation site resulted in the design flood discharge analysis being carried out. This study focuses on comparing the magnitude of flood designs from different times, namely Q5th, Q10th, Q25th, Q50th, and Q100th. After the flood discharge is obtained then it is used to calculate the dimensions of the Sand Pocket building. Each time that is used to calculate dimensions produces different dimensions in the building. The dimensions of the building that are affected in Main Dam and Sub Dam are effective height, upstream slope (m), flow height above the Main Dam, guard height, foundation depth, and the base width of the Main Dam and Sub Dam. In the appron is the length of the floor and the thickness of the appron floor. Then the last is the upstream side of the Main Dam wing. The selection of re-ordering determines the amount of discharge that will be generated and also affects the dimensions of the Sand Pocket that will be planned.ABSTRAKDebit banjir rancangan menjadi parameter penting dalam perencanaan desain bangunan air. Saat analisis debit banjir rancangan, pemilihan kala ulang menjadi hal yang krusial karena akan menentukan besarnya debit banjir rancangan. Pemilihan kala ulang disesuaikan dengan karakteristik Daerah Aliran Sungai (DAS). Lokasi rencana Sand Pocket berada di kali Woro, Klaten, Jawa Tengah. Tidak tersedianya data debit banjir rancangan pada lokasi pengamatan mengakibatkan analisis debit banjir rancangan ini dilakukan. Penelitian ini berfokus untuk membandingkan besaran debit banjir banjir rancangan dari kala ulang yang berbeda yaitu Q5th, Q10th, Q25th, Q50th, dan Q100th. Setelah debit banjir didapatkan kemudian digunakan untuk menghitung dimensi bangunan Sand Pocket. Setiap kala ulang yang digunakan untuk menghitung dimensi menghasilkan dimensi bangunan yang berbeda di beberapa bagian. Bagian dimensi bangunan yang terpengaruh pada Main Dam dan Sub Dam adalah tinggi efektif, kemiringan hulu (m), tinggi aliran di atas mercu, tinggi jagaan, kedalaman pondasi, dan lebar dasar Main Dam dan Sub Dam. Pada kolam olak adalah panjang lantai dan tebal lantai kolam. Kemudian yang terakhir adalah kemiringan sisi hulu sayap Main Dam. Pemilihan kala ulang menentukan besaran debit yang akan dihasilkan dan berpengaruh pula terhadap dimensi Sand Pocket yang akan direncakanan.

The sequential quadratic programming method is introduced in arch dam shape optimization design. In the optimization computation, the arch dam volume is taken as objective function, and the calculation is realized by automatically considering loading process, equivalent stress computation and simulation of shape optimization for arch dam based on FEM. A parabola arch dam is used as a numerical example. The result shows that the optimized figure is much safer and more practical, which indicates that the SQP method is an effective way for optimization design of arch dam shape.

The main parameters of the earth dam, peculiarities of its erection and operation are described. The article notes the importance of ensuring a high degree of reliability of water structures constructed near major cities. It is especially important to monitor the condition of retaining structures with long service life. The factors influencing the change of the initial design conditions of operation of the Kuibyshev run-of-river unit dam are discussed. The results of examination of the geometric parameters of the body of the dam, performed at different periods of its maintenance, are analyzed. Examination results revealed significant deviations of the elevation marks of the earth dam surface on the upstream side from the design values. Possible causes of the discrepancy between these parameters and the design solutions are considered. The conclusion is drawn that the most likely reason for these features of the dam design lies in the initial incompleteness of construction. The measures for carrying out repair work to improve the reliability of the earth dam are being recommended.

Abstract:

The RFPA3D is used to establish a fine finite element model of 6.63 million elements, which realizes the fine simulation of the stability of the Xiluodu arch dam under layered, overall, multiworking conditions and multistress fields, and the cracking and failure process under overload. The structural design scheme of the arch dam and the corresponding foundation treatment design are evaluated. The model fully reflects the measures of dam shape structure design, angle fitting structure design, and foundation concrete replacement in the Xiluodu arch dam technical design stage. The RFPA3D adopts the mesoelement elastic damage model, which considers the Mohr–Coulomb criterion of shear fracture and the maximum tensile failure criterion, and assumes that the mechanical properties of the element satisfy Weibull distribution to consider its heterogeneity. The simulation results show that, under normal load conditions, the dam foundation surface after comprehensive reinforcement has better overall stability, the stress and deformation of the dam body have good symmetry, and the overload factor of crack initiation under overload calculation K1 = 2P0 (P0 is normal water load), the nonlinear deformation overload factor K2 = 3.5–4P0, and the limit load factor K3 = 7.5–8.0P0, dam safety can be satisfied. The RFPA3D is used to establish a superlarge fine model to study the overall stability of the high arch dam, which provides an effective method for analysis and research of other large hydraulic projects in the world.

Abstract:

Safe dam design, especially when the dam is likely to erode when submerged, must take into account wave surge. The lack of data for small structures built in a forest environment is a problem when assessing this surge. This paper proposes an approach to assess wave surge for these structures. The proposed approach is based on relationships developed by Saville et al. (1962) for inland lakes. An example to illustrate the application of this approach is discussed in the framework of the Quebec Dam Safety Regulation (Quebec Government 2002).Key words: dam design, dam safety.[Journal translation]

Abstract:

The planning, design, and performance of the Yele asphalt-core rockfill dam in Sichuan Province, China, are presented. The dam has a maximum height of 124.5 m, is located in a very seismic region with inclement climate, and is founded on a geologically complex foundation, partly resting on a deep and pervious alluvial overburden and partly on bedrock. With these site conditions only an embankment-type dam was considered feasible, and three different options were considered for the design of the impervious barrier: (i) earth core, (ii) concrete facing, and (iii) asphalt core. The third option was chosen. The design is based on extensive analyses and laboratory tests, and a special model test was performed to study the behavior of the connection between the narrow asphalt core and concrete plinth. An impoundment test was performed when the dam was 73 m high to test the imperviousness of the constructed core and the connections between (i) the core and plinth and (ii) the plinth and foundation cut-off wall. An extensive field monitoring program was implemented. Design predictions are compared with field performance observations of the core and its interaction with the adjacent transition zones.

Abstract:

Concrete cut-off wall has been widely used in the reinforcement project of earth-rock dam. Its design method and construction technology are comparatively mature, but comprehensive study of interaction of cut-off wall and dam is few, especially for the case that new cut-off wall built in earth-rock dam. In order to discuss the principal and law of interaction of cut-off wall and earth-rock dam in the reinforcement project, seepage field and stress field coupled numerical model was established by using ABAQUS. The contact between the wall and the dam together with the coupling of the stress and the seepage were taken into account in the model. Through coupling calculation of typical earth-rock dam project, the results show that, the model is feasible to simulate the interaction of cut-off wall and earth-rock dam, and the method can provide reference for design calculations of cut-off wall in reinforcement project of earth-rock dam.

Abstract:

The dam foundation seepage control is usually a main work of dam design. This paper presented the effects of different concrete curtain boundary conditions on the dam foundation seepage control through numerical calculation with the finite element method. The results show that the depth of concrete curtain strongly depends on the permeability of dam foundation. The middle of curtain should be deeper than its sides if the permeability of central riverbed is higher. Therefore the design of curtain should be based on the numerical analysis of the dam foundation seepage with different curtain boundary conditions in order to make sure the safety and economy.
