摘要
文中以易门县铜厂中学 3 处边坡为例,通过实地调查以及钻探等勘测方法,基本查明了滑坡边坡的基本特征、地质条件、影响因素以及变形方式和破坏机理,对其边坡群稳定性进行了定性和定量分析,并针对性作出评价,最后得出,其在天然工况下为稳定到基本稳定状态,在暴雨工况下为欠稳定状态,在地震工况下为欠稳定到不稳定状态,这对后期治理起到了指导作用.
Abstract
In this paper,three slopes at Tongchang Middle School in Yimen County are taken as examples.Through field investigation,drilling and other survey methods,the basic characteristics,geological conditions,influencing factors,deformation mode and failure mechanism of landslide slopes are basically identified.The stability of slope groups is qualitatively and quantitatively analyzed and targeted evaluation is made.Finally,it is concluded that the slope is stable to basically stable state under natural working conditions.In the case of rainstorm,it is understable,and in the case of earthquake,it is understable to unstable,which plays a guiding role in the later treatment.
