陕北某黄土边坡稳定性分析及防治研究

The Study on the Stability and Prevention of a Loess Slope in Northern Shaanxi

以陕北某黄土边坡为例,分别采用极限平衡法和强度折减法对其进行了稳定性计算,并对两种方法进行了对比。结果表明:两种方法得到的滑动面基本相同,该滑坡目前稳定性较差,处于极限平衡状态,需要进行治理设计。针对计算结果,提出了治理方案建议。

A loess slope of northern Shaanxi as an example,the stability calculation of the slope is done based on the limit equilibrium method and strength reduction method,and the comparison of the two methods is made. The results show that the sliding surfaces determined by the two methods are basically same. The stability of the slope is poor and in the ultimate state,and the control design is urgently needed. According to the calculation results,suggestions on the management scheme are put forward.
