摘要
以鞍山地区为例，阐述了层次分析—模糊综合评判方法（ＡＨＰ－ＦＵＺＺＹ）在鞍山岩溶地面塌陷环境地质质量评价中的应用。评判结果表明，地下水位升降情况、断裂密度、粘土含砾层厚度及基岩富水性对岩溶地面塌陷的形成起决定性的作用。根据８７４个单元的评判结果，将鞍山岩溶塌陷环境地质质量划分为极差、较差、中等、优良等５个区，这一结果与实际情况较为吻合。
According to the actual conditions, the writers select 8 factors that can cause collapses, and evaluate the environmental geological quality comprehensively by the AHP FUZZY method. The results of AHP show that the density of the fractures, water level, RQ and the thickness of the upper cover are the major factors that can cause collapses. On the basis of the evaluation results on 874 units, the environmental geological quality of karst collapses can be divided into 5 levels, that is, worst, worse, middle, good and so on, which is identical with the actual situation.
