Abstract:Based on an engineering example of asymmetrically loaded deep excavation, the theoretical foundations of constitutive models of HS and HSS were analyzed. The contrast analysis of HS and HSS constitutive model applied in the numerical simulation of asymmetrically loaded deep excavation was studied. It is found that the deformation of the numerical simulation by HSS constitutive model is more close to monitoring data.

Keywords:constitutive model; asymmetrically loaded deep excavation; hardening soil model; hardening soil model with small-strain stiffiness
