| 摘 要： | 采用有限元方法,对复合地基中的单桩在不同土体分层状况下受水平荷载作用的情况进行了3维数值分析。通过比较不同层况、桩长、桩径、褥垫层厚度下受水平荷载作用的桩体轴向应变的性状,得到复合地基中桩体的断桩点随土体分层状况改变而变化的规律。

| Abstract: | This article adopts the finite element method to analyze, in a three dimensional way, the property of a single pile of the composite foundation under the action of the horizontal load in different soil layers conditions. Through the property of axial strain under different improvement parameters, such as soil layer conditions, pile length, pile diameter and mattress thickness, we get the viriation regulation of position of the body of the pile, where the fracture of the pile most probably appears in the composite foundation along with the change of different soil layer condition. |
