摘要
通过勘察,结合工程类比方法,分析了重庆某牵引式滑坡的形成机理,明确其发生滑动的主要动力源;采用传递系数法及有限元数值模拟法对滑坡体在天然工况和暴雨工况下进行了稳定分析,提出了一套有针对性的治理方案,现场监测表明,该分析结果准确,治理方案较为恰当,治理效果明显,对同类牵引式滑坡研究具有一定指导意义。
Through detail geotechnical investigation and surveying,and combining with the engineering analogy method,the formation mechanism of a typical retrogressive landslide in Chongqing was analyzed.The main source of power for the landslide slipping was defined.Then the transfer coefficient method and FEM analytical method were used to calculate the stability of landslide under working condition of natural and rainstorm.Following,the reasonable treatment schemes were put forward.A good treatment effect has been obtained as the locale observation and monitoring.Therefore this treatment can provide reference for similar retrogressive landslide.
