摘要
本文采用基于温克尔假定的弹性地基梁计算法,提出了水平分层地基中,受竖向荷载作用桩的刚度传递计算法和受水平荷载作用桩的柔度传递计算法。并且分析了桩土条件对桩的竖向刚度、水平刚度、摇摆刚度及水平摇摆刚度的影响,然后根据等效桩和桩侧土刚度矩的概念,研究了任意地基中桩刚度与它的等效桩及桩侧土刚度矩之间的关系,从而提出了任意地基中桩刚度的近似计算方法。
Based on the Winkler model of elastic foundation beam, the stiffness recursion formula of a pile in the layered soil under the action of the vertical or horizontal load has been developed in this paper. The influence of soil condition on pile stiffnesses, and the relationship of the pile stiffness with its equivalent pile and the stiffness moment of soil beside the pile in any soil, according to the concepts of the equivalent pile and the stiffness moment of soil beside the pile, are studied. Finally, the approximate calculation method of the pile stiffness in any soil is presented.
