摘要：

地基系数法是弹性抗滑桩内力计算的常用方法，基于地基系数“m-k”法的基本原理，将抗滑桩作为整体进行内力分析，提出了弹性抗滑桩全桩内力计算的反力荷载法，详细推导了有关计算公式；运用Matlab语言编写了全桩内力计算和图形处理程序，可对全桩进行整体分析，不需要像传统方法那样以滑动面为界将抗滑桩分成受荷段和锚固段分别计算其内力；与有限差分法相比，无需利用滑动面处的连续性条件进行迭代计算；计算实例表明，其方法与传统方法计算结果能很好吻合，图形处理结果有利于抗滑桩结构设计，且程序运行时间短，可提高抗滑桩内力分析效率。

Abstract:

foundation coefficient method is a common method for calculating internal forces of a elastic anti-sliding pile. Based on coefficient “m-k” method, the counterforce load method is presented to calculate the internal forces of a whole pile. The corresponding formula are derived in detail. The calculation program of internal forces for a whole pile is designed with Matlab. The pile can be analyzed as complete entity. It is not necessary to divide the anti-slide pile into loading segment and anchoring segment by the sliding surface like the tradition methods. Compared with the finite difference method, the presented method does not make use of the continuity condition at the sliding surface and the iteration and test calculation. An example shows that results coincidence well comparing the traditional method can be obtained. The results of figure treatments by the program can optimize the construction design of anti-sliding piles; and it demands very short time for the calculation and can improve the calculation efficiency.

Key words: elastic anti-sliding pile, whole pile internal force, foundation coefficient “m-k&rdquo, method, counterforce load method
