滑坡滑带的抗剪强度参数是滑坡稳定性分析的基本参数,直接影响着工程治理方案和治理工程量。基于对滑坡滑带地质性质的分析,提出了滑带土抗剪强度参数的确定方法和经验值,对电网工程滑坡勘察和治理具有参考价值。

Landslide is one of the common geo-hazards for power grid engineering.The mechanical parameters,the shear strength parameters in particular,of the sliding zones are the basic parameters for stability analysis of landslides,which have a direct impact on the scheme and engineering amount of landslide treatment.Based on a classification of landslide sliding zones,this paper makes a study on the properties of sliding zones,proposes some methods for determination of the shear strength parameters and summarizes the relevant empirical values from some hundreds of existing landslides,which will be useful and can be referred to in investigation and treatment of landslide hazards for power grid engineering.
