- Abstract:
-
A realistic hyperbolic model is used to describe the nonlinear interaction between soil and cement-soil retaining wall, and assuming that the wall is rigid, and considering the weight of the wall and the shear and overturning resistance of the subsoil, a nonlinear equation system representing equilibrium is obtained. When solved, it is converted into extreme points for extreme value problems. The results show that the horizontal displacement of the hyperbolic model and the linear model are basically similar with the excavation depth, but the results of the hyperbola model are greater, and with the increase of the excavation depth of the foundation pit, the difference in the soil pressure distribution calculated by the two models is increasing, that is, the influence of soil nonlinearity is becoming more and more significant.
