摘要
边坡治理是水库工程建设的难题之一,我国已经建设了相当数量的水库工程,但由于水库建设和运行期间产生人为干扰,水库涉水边坡的稳定性以及变电站的正常运行都会受到一定程度的影响,严重时还会造成一些边坡出现滑塌等问题。通过工程实际案例,分析了边坡主要不利因素,利用极限平衡法计算不同工况下白稳定系数,对边坡进行稳定性分析,提出可以利用抗滑桩、建立排水系统等措施提高抗滑力,最后得出地震作用是影响边坡稳定性最大的因素。
Slope treatment is one of the difficulties in reservoir engineering construction.China has already constructed a considerable number of reservoir projects.However,due to human interference during the construction and operation of the reservoir,the stability of the reservoir's wading slope and the normal operation of the substation will be affected to a certain extent,and in severe cases,it may also cause some slope collapse and other problems.Through practical engineering cases,this paper analyzes the main unfavorable factors of the slope,uses the limit equilibrium method to calculate the white stability coefficient under different working conditions,and conducts stability analysis on the slope.It proposes measures such as using anti slip piles and establishing drainage systems to improve anti slip capacity.Finally,it is concluded that seismic action is the biggest factor affecting slope stability.
