摘要

基于简化Bishop法,对锚固路堑边坡进行稳定性分析。将锚固力简化为作用在土条底面上的外力,推导了锚固路堑边坡的安全系数计算公式,将针对自然边坡稳定性计算的简化Bishop法扩展至锚固路堑边坡稳定性计算,并通过具体算例验证了其正确性,对于今后类似的锚固路堑边坡稳定性计算提供了重要参考。
        The stability analysis on the side slope of anchored cut is made based on the Bishop simplification method. The calculation formula of safety coefficient for side slope of anchored cut is derived by simplifying the anchoring force to an external force on the bottom surface of soil strip. The Bishop simplification method for the stability calculation of natural side slope is extended to the stability calculation of side slope of anchored cut,and its correctness is verified through the specific calculating example,so as to provide important reference for similar stability calculation of side slope of anchored cut in the future.
