Stability Analysis of Multi-struts Diaphgram Wall

The use of Multi-struts diaphgram wall is more and more broad.The simulation of excavation and support on one multi-struts diaphgram wall project is carried out using the software FLAC(3D).During the simulation,the Mohr-Coulomb model is used and shell elements are applied on the wall and strut structure.This simulation offers the settlements behind the wall,lateral-displacements and moment of the wall in every step.It is a reference for design and construction.
