摘要
根据门城镇采空区实地勘查资料,采用两级模糊综合评判的理论与方法,建立了地面塌陷危险性评判模型及评判指标,对采空区地面塌陷危险性进行了分区预测,其结果与实际情况吻合较好,可作为该区的开发建设规划及地质灾害防治工作的依据。
A math＇s model of fuzzy comprehensive evalualion is used to divide the degrees of risk of gob collapse at Meneheng town. Eleven evaluating factors are chosen which influence the risk degrees of gob collapse mostly, these factors are divided into three classifications, which are geology, exploitation and the characteristic of land. using the two-stage fuzzy comprehensive evaluation, the risk degrees of ground collapse at Mencheng town are divided into three classifications, that is, risk zone, relative risk zone and relative stability zone. The evaluating results can reflect the facts better, and can provide a scientific basis for the disaster control and the city planning.
