| Abstract: | Based on an urban bypass expressway widening project,the finite element technique using a Mohr-Coulomb elastic-plastic constitutive model was applied to analysis the feasibility of using diaphragm wall to improve the soft clay.Conclusions are achieved that the diaphragm wall should meet with the requirement.Moreover,the appropriate location,strength and thickness of the diaphragm wall were put forward. |
