基于GLE通用条分法和强度折减法,分别利用天然和饱水状态强度参数,计算了滴水崖Ⅰ号滑坡的稳定性,两类方法揭示的滑动面空间形态接近,安全系数也相近,说明两类方法用于滑坡稳定评价是稳定的、合适的。通过设计的膨胀角、变形参数强度折减法计算方案,分析发现膨胀角和变形参数对计算结果影响不大;饱水状态下滑坡是不稳定的,所以设计了锚固方案,两类方法计算所得该滑坡采取锚杆支挡措施下的稳定性满足工程安全等级要求。
Based on the GLE generalized strip method and the strength reduction method, the stability of the Dachoucai Ⅰ landslide was calculated by using the natural and saturated state strength parameters respectively. The spatial patterns of the sliding surface revealed by the two methods are similar and the safety coefficients are also similar The class method used for landslide stability assessment is stable and suitable. Through the design of the expansion angle, the deformation parameter strength reduction method to calculate the program, the analysis found that the expansion angle and deformation parameters have little effect on the calculation results; landslide is not stable under water saturation, so the design of the anchoring scheme, the two methods calculated The stability of the landslide under bolt support measures meets the requirements of engineering safety grade.
