摘要
人类工程活动、大气降雨是诱发地质灾害主要的外因。通过反演分析,滑带土的内摩擦角比粘聚力对滑坡稳定性影响大。通过稳定性计算分析,该滑坡在天然工况下处于欠稳定状态,暴雨工况下处于不稳定状态。针对该滑坡体的特征及现场条件,建议采用抗滑桩+截排水的综合治理方案。
Human engineering activities and atmospheric rainfall are the main external causes of geological disasters.Through the back analysis,the internal friction angle of sliding zone soil has greater influence on the stability of landslide than cohesion.Through stability calculation and analysis,the landslide is in an unstable state under natural condition and unstable state under rainstorm condition.According to the characteristics and site conditions of the landslide,the comprehensive treatment scheme of anti slide pile+interception and drainage is recommended.
