滑坡稳定性的模糊综合评定——以陕西渭南地区重点滑坡为例

FUZZY SYNTHETIC VALUATION ON STABILITY OF LANDSLIDE—TAKING BIG LANDSLIDES IN THE WEINAN REGION OF SHAANXI PROVINCE

本文选用地形地貌、岩性结构、构造、大气降雨、水文地质和人类活动6个定量化的环境因子作为评定滑坡稳定性的标志。利用模糊综合评判方法,对陕西渭南地区数十个滑坡的目前稳定性作了分级判别。按渭南地区的实际情况将其稳定性分为稳定滑坡、较稳定滑坡、不稳定滑坡三级,其结果与实际较为符合。

Choosing landform, rock structure, Precipitation, hydrogeology and human activity as indices, a stability adjudging of tends of landslides in the Weinan region is made by Fuzzy synthetic valuation. There are three classes, that is stable, more stable and unstable landslides, which is consistent with the actual situation.
