摘要
本文从岩土破坏的本构律出发建议了斜坡失稳的滑动—弱化模式,然后对平面倾斜面、幂函数型滑动面、园弧型滑动面等简单的情形进行了斜坡失稳的动力学分析,得到了滑坡速度分布的表示式:讨论了坡底速度、滑坡止滑位置等问题。
A slip—weakening model of landslide has been proposed from constitutive law of rock and soil in the paper .Employing this model,dynamic analyses of slope instability have been made for several types of slip surface, such as inclined plane type,power function type and circle type.The expressions of slip speed of landslides have been given,and such problems as the slip speed at thebottom of landslide and the stop position of slip have also been discussed.
