| 摘 要： | 应用静力弹塑性有限元方法分析了群桩刚性桩复合地基在水平荷载作用下的反应规律 ,考察了不同设计参数对复合地基水平受力性能的影响 ,得到了水平荷载作用下桩身内力的分布规律。计算结果表明 :竖向荷载的大小对复合地基的水平承载力以及在水平荷载作用下的破坏模式有所影响 ;适当厚度的垫层可减小桩所分担的水平荷载 ,有利于桩身的安全。

| Abstract: | The behavior of rigid pile composite foundation under horizontal load is analyzed by using elastoplastic finite element method. It is investigated that the effects of different design parameters on the horizontal forced behavior of the composite foundation, with which the distribution law of internal forces along pile subjected to horizontal load is also obtained. Calculations show that vertical load at proper level will enhance the horizontal load bearing capacity of composite foundation. Due to the effect of the cushion layer in the composite foundation, the horizontal load transferred to piles will be decreased and the pile will be safer. |
