According to the characteristics of the geology and structure
a sub-model which contains the mechanical characters of the underground continuous wall is built. Based on ABAQUS software
Mohr-Coulomb failure criterion and non-associated flow rule are used to simulate the course of construction. The stresses and displacements of the structure are analyzed amply. Meanwhile
based on the strength reduction method
the stability of the structure is studied. The results show that the constructing method of the groundsill using underground continuous wall is reasonable and feasible. So
the underground continuous wall can satisfy the requirement of engineering.
