民采空区危险性两级模糊综合评判——以招远市北截村为例

Two-levl Fuzzy Comprehensive Evaluation on the Risk Degree of Mined-out Area by Villagers

在充分搜集资料的基础上,对招远市北截村民采空区进行实地勘查,从地质条件、灾害发育程度及采空区特征3个影响因素入手,选取了9个评判因子进行两级模糊综合评判,采取最大隶属度原则确定采空区危险性等级,并进行了评估分区。评判结果能较准确地反应实际情况,为该区地质灾害防治工作及开发建设规划提供了依据。

On the basis of collecting adequate information,investigation in the mined-out area by villagers in Zhaoyuan city has been carried out.Starting with three factors of geological conditions,development degree of hazards and characteristics of the mined-out area,nine evaluation factors are chosen to do the two-levels fuzzy comprehensive evaluation.At the same time,choosing the principle of maximum membership degree,risk degrees of the mined-out areas have been divided,and the risk degree zones have been divided as well.All the evaluating results can show the real conditions accurately.It will provide some references for the prevention and control work of local geological hazards and the development and construction plan.
