摘要
由于城市建设及人类工程活动越来越强烈,边坡灾害的数量快速增加。地下水的渗流作用是边坡灾害的诱发因素,如在城区范围内的赵树岭滑坡等特大型滑坡,给当地经济社会发展和人民生命财产带来了极大危害。因此,研究地下水渗流作用对滑坡稳定性的影响具有十分重要的意义。本文基于极限平衡法,利用Seep/W模块对不同工况下的渗流场模拟分析,采用Morgenstern-Prince法对其稳定性进行研究。在此基础上,以三峡库区巴东县赵树岭滑坡为例,对地下水渗流作用下的滑坡稳定性进行分析,结果显示赵树岭滑坡现状整体稳定,没有整体变形迹象,也无局部较大规模变形迹象和局部变形迹象。
As the urban construction and human engineering activities become more and more intense,a large number of slope disasters come along with it.Groundwater seepage is the inducement factor of slope disasters.In the urban area,there are super-large landslides such as Zhaoshuling landslide,which bring great harm to the local socio-economic development and the security of lives and property of the people.Therefore,it is of great significance to study the influence of groundwater seepage on landslide stability.Based on the limit equilibrium method,this paper uses Seep/W module to simulate and analyze the seepage field under different working conditions,and uses Morgenstern-Prince to research the landslide stability.On this basis,taking Zhaoshuling landslide in Badong of the Three Gorges Reservoir as an example,analysis of the landslide stability under the action of groundwater seepage,the results show that the present condition of Zhaoshuling landslide is global stability.There is no overall deformation sign,and no local large-scale deformation or local deformation sign.
