| 摘 要： | 将模糊信息分析方法应用于公路滑坡稳定性分析。运用模糊信息分析中的模糊信息信息分配、信息集中等方法,在云南元磨高速公路滑坡的50组公路滑坡资料中选取了滑坡高度、坡度、组成物质的粘聚力、内摩擦角等重要影响因素,建立了其与滑坡稳定性之间的模糊关系,得到相应的滑坡稳定性分析数学模型。应用该模型对该区域其他滑坡进行验证,其效果良好,故该方法可较好的应用于实际。

| Abstract: | The fuzzy information analytic method is used in the stability analysis of landslide on expressway in Yun-Nan province. This paper applies the fuzzy information analytic method such as information distribution and information concentration to the 50 sets of data of landslides. These landslides are located on the Yuanjiang-Mohei expressway in Yunnan Province. The fuzzy relationships are developed for the landslide stability with respect to the height, angle of slope, cohesion, and internal friction angle of landslide. These parameters are the important influence factors. The corresponding model of landslide stability analysis is established. The developed model is verified with other landslide in the area. It is indicated that the model has low error and good effect. |
