摘要
Abstract
A retrogressive landslide presents progressive failure in the process of deformation,with the shear strength parameters of sliding zone soil being different at various stages of deformation.How to obtain economically reasonable parameters is of great significance to landslide emergency response and engineering treatment.In this paper,the limit equilibrium and numerical simulation methods are used for inversion of shear strength parameters of the sliding zone soil of the retrogressive landslide,and the results are compared with those obtained by geotechnical test and engineering analogy methods,indicating that differences exist in the parameters obtained by different methods.In the engineering practice,the applicable conditions of each method should be fully considered,and the reasonable parameters should be selected according to the state of the landslide and the treatment stage,so as to provide a basis for the emergency response and engineering treatment of the landslide.关键词
