公路滑坡滑带土抗剪强度参数选取方法研究

摘要

以羊道沟滑坡为工程实例,研究滑带土抗剪强度参数选取方法。利用反演分析结合室内试验和经验系数,得出滑带土抗剪强度参数（c、φ）值。研究表明：反演分析与多种方法的综合确定的滑带土抗剪强度参数更为合理,能有效地满足工程要求。%Taking Yangdaogou landslide for example,the selection method for the shear strength parameter of slip zone＇s soil is studied.Then,combining with laboratory and empirical coefficient,the shear strength parameters（c,φ） of slip zone＇s soil are obtained by using inversion analysis.The study results show that the shear strength parameters of slip zone＇s soil determined by the inversion analysis integrated with a variety of methods are more reasonable,and can effectively meet the requirements of engineerings.
