本文从斜坡的地貌,工程地质,水文地质、诱发因素等特征出发,找出了影响滑坡的主要因素,对33个堆积层斜坡进行调查,统计出各因素对于坡体稳定性的隶属函数值。建立了用于判定斜坡稳定性的二阶模糊数字模型.最后给出两个斜坡在不同条件下的稳定分析例子,并用条分法计算作了验证,所得的结论与现场实况基本相同。根据斜坡失稳机制,提出了滑坡整治的方法。
In this paper, the main factors affecting the landslide are found out from the characteristics of slope landform, engineering geology, hydrogeology and provocative factors. The investigation of 33 ravines is carried out, and the membership functions of each factor are analyzed. A second-order fuzzy numerical model is established to determine the slope stability. Finally, the stability analysis of two slopes under different conditions is given and validated by the striping method. The conclusions obtained are basically the same as those on the scene. According to the instability mechanism of slope, a method of landslide remediation is put forward.
