A solution procedure using boundary element method is presented for seepage analysis of earth dams involving drawdown of the water level in the reservoir. Applicability of the boundary element method is evaluated by comparing the predicted results from the boundary element method with the measured results from laboratory model test and field observations from earth dams. A simple and effective extension to the boundary element method for solving Laplace'S equation (∇ 2 u = 0) for boundary value problems is presented to solve steady confined and (or) steady unconfined seepage problems in zoned anisotropic mediums. Sample problems indicating the accuracy of Cited by: The momentum force on the right hand side of () is usually neglected in the seepage flow analysis of elastic porous media known as the consolidation analysis in soil mechanics. The system of () and () is similar to that of governing equations in the theory of : G. Aramaki, K. Onishi, T. Kuroki. This paper presents a practical approach for reliability analysis of steady-state seepage by modeling spatial variability of the soil permeability. The traditional semi-analytical method; named Scaled Boundary Finite-Element Method (SBFEM) is extended by a coded program to develop a stochastic SBFEM coupled with random field by: 6.
The methods of numerical solution, such as finite element [5,6,7,8,9,10,11], finite difference , finite volume  and boundary element , were used to analyze the phenomenon of seepage. In this research work, finite element approach is employed to solve the governing differential equations pertaining to seepage through body of dam its foundation. For this purpose, the foremost focal point is discretization of domain into finite elements. The scaled boundary finite-element method (SBFEM) a recently developed semi-analytical technique is applied to the analysis of confined seepage flow. This method combines the advantages of the finite-element method and boundary element method. In this scheme only the boundary of the domain is discretized, no fundamental solution is required. Finite Element Method (FEM) Because of the prominence of the finite element method (FEM) as an analytical tool in seepage analysis of dams and in the various SOFTWARE discussed later, an introduction on FEM is given in the following paragraphs.File Size: KB.
finite element free surface seepage analysis 15 In equation (2) p is the fluid pressure, y is the unit weight of fluid and z is the elevation at the point under consideration. From the beginning, the emphasis is on the implementation of the method into computer programs which can be used to solve real problems. The book covers two- and three-dimensional linear and non-linear analysis in potential flow (heat flow and seepage) and static elasticity. A boundary‐element solution procedure is illustrated and applied to the analyses of both steady‐state and non‐steady‐state unconfined seepage problems. An effective solution procedure for the finite element analysis of free surface seepage problems is presented. The solution algorithm employs a non-linear permeability description of the material and avoids iteration with the finite element by:
