斜坡地形桩土相互作用下初始地应力场的处理

On treatment methods at initial ground stress field under pile-soil interaction of sloped terrain

考虑桩土接触行为的影响,采用大型有限元软件ANSYS进行了斜坡地形的初始应力有限元模拟,算例表明该方法可以很好的消除初始位移场,从而较好的保留初始应力场,为研究各种岩土问题提供了一种处理复杂初始应力场的有效方法。

Considering the influence of the soil-pile connection,the paper adopts the large-scale finite element software ANSYS,to have the initial stress finite element simulation of the sloped terrain,and proves by the calculation example that the method can eliminate the initial displacement field effectively,so the initial stress field can be maintained in a better way and provides the effective method to treat the complicated stress field in various geotechnical problems.
