摘要
通过桩径或桩长的改变对桩竖向支承刚度的影响,建立了考虑桩竖向支承刚度的桩-承台共同工作分析模型。工程实践表明,这种优化设计思想可以使群桩中的每根基桩承载力得以充分发挥,达到了桩-承台共同工作的优化设计目的。
Based on the influence of difference of the diameter or length of bored pile on the vertical stiffness of pile,an analytical optimum design model of interaction between pile group and bearing platform is proposed with the vertical stiffness of pile into account. The bearing capacity of each pile could be fully utilized and the interacting characteristics of pile and platform is verified by means of engineering practice.
