摘要
应用Matlab软件PDE工具包中椭圆型方程模拟静力压桩挤土产生的应力场,指出挤土应力沿外径向递减;土与桩界面挤土应力随着桩与土体的模量比的减小而减小,随着土体泊松比的增大而减小。
The paper adopts the stress field formed by simulating the squeezing soil of the static pressed piles with the elliptic equation in PDE toolkit in Matlab software, points out the squeezing stress reduces along the direction of the external diameter, and the squeezing stress between the soil and the pile interface reduces along with the modulus ratio between the pile and the soil, and still reduces along with the increasing soil poisson.
