Three dimension numerical model was set up to discuss the soil arching effect of passive piles due to soil lateral displacement.
采用三维数值模型模拟土体水平位移条件下被动桩的成拱效应。
Numerical examples illustrate the effect of soil-structure interaction on the structures, and deformations of a structure compared with rigid body displacement under gravity second order action.
数值算例表明，土-结构动力相互作用对结构的位移产生较大的影响，由此所引起的重力二阶效应可能使结构抗倾覆性能偏于不安全。
Then, the effect of model parameters on displacement of soil and inner stress and displacement of bearing pile were discussed and rule of pit deformation was studied too.
