摘要： 通过对锚杆抗滑桩在工作状态下的受力进行分析,给出了嵌固深度的计算模型.分别运用被动土压力法、滑移线法和弹性楔体法求解出了滑动面下的桩前土抗力,进而利用该计算模型求得锚杆抗滑桩的嵌固深度.最后利用模型试验测试结果对计算模型进行了验证,并选用适当的工程算例对研究内容进行了分析讨论.结果表明该计算模型给出的锚杆抗滑桩嵌固深度比较合理.

Abstract: Analyzing an anchored pile against landslide under loading conditions, its built-in depth was studied with a model developed to calculate it. With the solution given to the resistance to earth against the anchoraged pile end under slip plane by ways of passive earth pressure, slip line and elastic wedge, the built-in depth was determined using the model. The calculation model was verified by relevant testing results and discussed in combination with a numerical example chosen properly form engineering practice. The results showed that the calculation model is comparatively reasonable for the built-in depth of anchored piles against landslide.
