摘要
基于Winkler地基模型,建立分层土中单桩的荷载传递矩阵,并考虑被动桩与桩周土的相互作用,建立被动桩的位移控制方程,得到两根桩的相互影响系数α.提出了刚性承台下受荷群桩的位移内力计算的解析方法,并和有限元计算的结果进行了比较,得到了较好的一致性.
This paper presents a simple analytical method for determining the settlement and intemal forces of loaded pile groups with rigid cap in layered soil. The load transfer matrix is obtained on the basis of Winkler model and the interaction factor a between two piles is determined by the settlement governing equilibrium equation of soil around passive pile. The result of the present approach agrees well with that of finite element method.
