| Abstract | Applying advanced numerical analysis is necessary in deep excavations to ensure successful execution and prevent problems of damage to the adjacent structures/facilities due to excessive movement. Numerical modeling of deep excavations using Finite Element Method (FEM) of analysis has become increasingly popular and is a powerful analytical tool. In this research, soil parameters are determined through back-analyzing the performance of a case study in Hochiminh city based on observed data. Analysis is performed by Finite Element program PLAXIS version 8 utilizing the conventional Mohr-Coulomb model for soil behavior. After that, sensitive analysis on factors affecting is carried out. The following is presented: 1) Review of empirical and numerical prediction methods for deep excavation supported by the diaphragm wall; 2) Back-analysis of a case study from Hochiminh city; 3) Study of the effect of soil stiffness, soil strength, pre-stressing support, and the un-drained behaviour on the performance of the diaphragm wall. |
