滑坡稳定性判别的非计算方法

The Non-computation Method to Differentiate the Stability of Slope

用计算来确定滑坡的稳定性 ,由于参数选取存不确定因素 ,就必然导致了其计算结果的不确定性。而滑坡稳定性判别的非计算方法 ,是通过对滑坡发育程度、形成条件的综合分析来确定滑坡的稳定程度的方法。文中通过归纳分析滑坡的形成条件 ,然后从滑坡地貌条件、动力作用、堆积物特征、诱发因素等方面详细阐述了滑坡稳定性判别的方法 ,最后 ,例举了川藏公路 10 2滑坡实例对该方法进行了验证。

It is one major task to differentiate the stability of slope of forecasting and controlling landslide ,and the exactness degree of differentiating the stability of slope will decide the success or failure of forecasting and controlling landslide. Usually we work out the stability coefficient of one landslide through some mathematical method to forecast the stability of slope. But we find some question in the process of calculating the stability of slope, for example we can't select the value of some parameter. One block of slope is used as calculating cell to work out the slope coefficient to differentiate the stability of slope, but we don't make certain whether this block can represent the whole slope and so on. These uncertain factors lead to acquire uncertain result consequentially. The non computation method of the differentiation of the stability of slope is one systemic method, which recurs to the development of landslide and formative condition to analyze landslide synthetically. The paper expatiates detailed the non computation method to differentiate the stability of slope from the formative condition landform condition, dynamic function?accumulation feature and derivational factors and so on. At last the paper validated this calculating method through #102 landslides in Road chuanzeng. Through synthetically analytical method to differentiate the stability of slope is one kind of applied method.
