摘要: 在桩-桩相互作用为弹性假定基础上,利用剪切位移法分析了层状地基土中桩-承台-土相互作用,考虑了加筋和遮帘效应对群桩基础沉降的影响,建立了层状土中考虑桩-承台-土相互作用的群桩承载特性分析方法。最后,对该方法计算结果与有限元计算结果和实测值进行了对比,结果验证了该方法的正确性。

Abstract: Based on the assumption of elastic pile-pile interaction, the pile-cap-soil interaction was analyzed by the shear displacement method, and an analytical method was then established to research bearing characteristics of group pile foundations embedded in stratified soil considering the reinforcement and barrier effects between piles and soil. Comparisons of the calculated results by the proposed method with the one by the finite element method and measured results, it was verified to be feasible. -
