接触元初始刚度系数对软土深基坑变形的影响分析

摘要

The Goodman element is used to simulate the interaction betweensoil and structure. Taking the deep foundation pit of Huangpu river walking tunnel as an example, the influence of stiffness of Goodman element on displacement of wall and surface settlement is analyzed with finite element method. This provides a basis for the choice of stiffness coefficients on numerical calculation of soft soil foundation pit and informationalized construction.%用Goodman单元模拟土与结构的相互作用，并结合上海黄浦江行人隧道浦西竖井深基坑工程，利用有限元方法分析了Goodman单元的刚度系数对地下连续墙的位移、墙后的地表沉降的影响，对软土深基坑的数值计算和信息化施工时接触元刚度系数的选取具有重要意义。
