摘要
为了综合判定滑坡发育的潜势度等级,在建立滑坡潜势度分析计算模型的基础上,定量评价并确定灾害发育级别;针对影响滑坡发育的多因素特征,应用模糊数学和层次分析理论(AHP),构建滑坡层次结构模型和模糊评判矩阵,确定潜势度指数;通过工程实例得出某滑坡属较高潜势度的结论,为滑坡灾害监测和防治提供了理论依据.
In order to determine the latent cevel of landslide development, an analytic and calculating model is established to make a quahitative evaluation of the disaster development level. According to the va- rious factors that affect landslide characteristics,guided by the fuzzy mathematics and the AHP theory, a model of the hierarchical structure of the landslide is set up with a fuzzy judgment matrix. Having the potential index,known,we can conclude with examples that the landslide has a higher potential degree. Our conclusion can provide a theoretical basis for landslide disaster monitoring and prevention.
