摘要
岷县滑坡灾害较发育,在人类工程活动和地震活动的扰动下,有些滑坡复活成为新的地质灾害隐患点,对滑坡周边居民生命财产安全构成了严重威胁。以下选择岷县八步川滑坡为典型案例,研究老滑坡因人类活动、地震活动而引起稳定性的变化,并通过定量的稳定性分析、滑坡推力计算,提出坡脚挡土墙+预应力锚索框架+局部坡面修整的防治方案。该方案简单易行,防治效果显著,具有普遍的指导意义。
The landslide disaster is very developed in Minxian County,in the disturbance of human engineering activities and seismic activity, some landslide revival as a new geological disaster pose a serious threat to life and property safety of the surrounding residents. In this paper MINXIAN Babuchuan landslide is selected as a typical ease study of quantitative analysis stability of landslide due to human activity, seismic activity, hen by thrust calculation, the retaining walls, prestressed anchor cable framework, local prevention and treatment measurement is proposed, the measurement is simple and easy and obtained good results, This has prevalent meaning of guidance.
