| 摘 要： | 介绍一种考虑桩筏相互作用的桩筏基础分析方法.将桩简化为作用在筏板下面的具有一定刚度的弹簧,弹簧刚度根据桩顶平均荷载和桩顶沉降来计算.群桩中桩顶沉降包括桩身压缩和桩端沉降两部分.群桩中桩身压缩由单桩静载试验得到的桩顶沉降与桩端沉降之差求得,群桩的桩端沉降由分层总和法计算.采用有限单元法计算程序,结合算例,说明了本分析方法的应用特点.

| Abstract: | The pile is modeled as an elastic spring with the stiffness of the corresponding pile,which is obtained by the average load and settlement of the pile group.The settlement of the pile in pile group consists of the compression of the pile and the settlement of the pile toe.The compression of the pile in the pile group can be determined by static load test.The settlement of the pile toe is calculated by layer wise summation method.The raft is modeled by the Finite Element Method(FEM) to obtain its internal force and deformation. |
