摘要：The interchange station of Foshan Metro Line 1 and Line 3 was regarded as the research object, and a three-dimensional finite element model was conducted by the software of Midas GTS to simulate the excavation of the metro station based on the constitutive model of hardening soil. The FEM results show that the diaphragm wall presents two deformation forms those are the kicking at the bottom of the wall and rigid translation into the pit. Comparing the numerical calculation and monitoring results of horizontal displacement of representative monitoring points of diaphragm wall under different excavation conditions, it is proved that the numerical results which based on the model of hardening soil is practicable in Pearl River Delta.
