摘要

将改进的层次分析法和模糊综合评判方法相结合

深入分析影响公路滑坡灾害危险性的影响因素

建立了综合评判指标体系并划分危险性等级。评价过程中首先确定了不同降雨情况下指标体系的动态权重系统

然后应用“梯形”隶属函数公式和专家经验赋值法分别测算连续型和离散型指标的隶属度

最终通过所构建的3级模糊综合评判模型进行了实例研究。研究结果表明

该方法用于极端降雨诱发公路滑坡灾害危险性评价具有适用性和合理性

结果可靠。

Abstract

The hazard assessment of the highway landslide induced by the extreme rainfall is a complicated systemetic issue.By combining the modified analytic hierarchy process and the fuzzy comprehensive evaluation

all the factors that influence the highway landslide are analyzed.And the comprehensive evaluation index system as well as the danger rating is established.In the process of evaluation

different rainfall's dynamic weighting system is fixed

and then the membership of continuous and discrete index are calculated respectively by using the trapezoid membership function formula and expertise assignment

and finally case study is carried out.It is shown that this method is suitable and rational to evaluate the highway landslide induced by extreme rainfall.
