中文摘要：

文章研究了深路堑高边坡中采用的多排预应力锚索抗滑桩内力计算方法。基于普通抗滑桩内力计算的地基系数法原理,考虑桩身和多排锚索位移的变形协调,提出了其内力计算的有限差分解法。与传统方法相比,该法通过编程计算,可很容易获得锚索拉力、全桩内力和位移值及其分布规律。工程实例计算结果与现场测试结果的对比分析表明,本文提出的方法可行,其计算结果较好反映了锚索桩的实际受力状态和变化规律。

英文摘要：

This paper discusses a new internal force calculation method of anti-sliding pile with multi-row pre-stressed anchors on the high slope engineering. Based on the principle of foundation coefficient method in calculating the internal force of the ordinary anti-sliding pile, considering the deformation consistence between multi-row anchoring cables and pile body, the finite difference method is presented to calculate its internal force. Comparing with the traditional method, this method is easy to compile a program to calculate the tensile force of anchors, displacement and internal force of the whole pile and it＇ s regularities of distribution. The field testing results and the calculating results are compared by an engineering example, it shows that the calculation results reflect the actual stressful condition of pile, and this calculation method is applied and reliable.
