简化Bishop法的扩展及其在非圆弧滑面中的应用

An extension of simplified Bishop method and its application to non-circular slip surface for slope stability analysis

在众多边坡稳定分析方法中,经典简化Bishop法的应用最为广泛,但此法只能求解圆弧滑面的安全系数。笔者提出了扩展简化Bishop法,它不仅保留了经典简化Bishop法精度高、易使用等优点,且能够计算非圆弧滑面的安全系数,是较为实用的边坡稳定分析方法。

The classical simplified Bishop method has been used widely in slope stability analysis; but it only can compute safety factor for circular slip surface. This paper suggests a new extended simplified Bishop method; it has all advantages of the classical simplified Bishop method such as high precision and easy usage, moreover it can compute the safety factor of slope stability for non-circular slip surface. The results of an example show that the method is a practical method for slope stability analysis.
