| 摘 要： | 采用有限元方法,对复合地基中的群桩在不同土体分层状况下受水平荷载作用的变形情况进行三维有限元分析。通过比较不同层的材料特性、桩长、桩径下受水平荷载作用的最不利位置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: | The finite element method is used to analyze,in a three dimensional way,the deformation property of pile group of a composite foundation under the action of a horizontal load in different soil layers conditions.Comparing the property of axial strain under different conditions,such as different material properties of soil layers,pile length,pile diameter and mattress thickness.It's obtained the variation law for the position in the pile of the composite foundation where fracture would most probably occur along with the change of different soil layer condition. |
