Comparison of Conventional Method with Elastoplastic Finite Element Analysis for Anchored Diaphragm Wall as Excavation Support System

In today’s era of the developing world, increase in population in the metropolitan cities have brought the need for multi-complex solution in civil engineering field, which used to result in maximum dependency to computer-depended software. Conventional as well as numerical analysis and parametric studies are required to represent the behaviors of the soil as well as retaining structure. Hence, the objectives are to investigate the effect of different parameters on retaining structures (anchored diaphragm wall) and comparing the analysis of conventional method using Geo5 software using finite element method (FEM) using Plaxis-2D software. It is noticed that for serviceability consideration, the conventional design method is unable to consider various parameters. So, to observe the structural behavior and the response of wall, the finite element method (FEM) is used to perform the numerical modeling. The parameters used in the study includes the depth of excavation and soil type. To achieve the objective of this study, these parameters are used to conduct the series of conventional analysis and finite element analysis (FEA). Results of these analysis were observed in terms of factor of safety (FOS), horizontal displacement, shear force, and bending moments induced in the anchored diaphragm wall.
