摘要:
采用比较符合实际的双曲线模型来描述土体与水泥土挡墙之间的非线性相互作用,并假定墙体为刚体,且考虑墙体重量与墙底土的抗剪和抗倾覆作用,得到了表示平衡的非线性方程组.求解时,将其转化为求极值问题的极值点.结果表明:双曲线模型和线性模型算得的水平位移随开挖深度变化的规律基本相似,但双曲线模型的结果较大,且随着基坑开挖深度的增大,两种模型算得的土压力分布的差异越来越大,即土体的非线性的影响也越来越显著.
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.
