虹金村堆积滑坡体的稳定性分析
|
摘要
以四川省涪江虹金村堆积滑坡体为例,依据滑坡体形成的条件,运用极限平衡法和有限元法,采用数值模拟对堆积滑坡体在天然工况、蓄水位工况的稳定性进行计算分析,得出相应的安全系数,为堆积滑坡体治理措施提供参考。
Taking the talus landslide at Hongjin Village, Fujiang, Sichuan Province as an example, with limit equilibrium method and finite element method, the stability of the landslide under natural condition and the storage level condition was calculated by means of numerical simulation according to the conditions how the landslide forms. Through the analysis, the corresponding safety factor was obtained, offering the references of control measures of talus landslide.
