可拓学在济南市地质灾害易发性评价中的应用

Application of Extension Method of Probability Evaluation of Geological Hazarads in Jinan City

介绍了可拓学的基本理论,并应用于地质灾害易发性划分。选取了岩土体类型、地形坡度、地质构造、已有灾害点数量、人类工程活动强度、多年平均降雨量为地质灾害易发性评价指标,运用层次分析法获得了评价指标的权重值,建立了基于可拓学理论的地质灾害易发性评价模型。以济南市为例,对可拓学模型的评价结果进行验证,该方法获得结果与实际情况吻合程度高,证明这一方法是切实可行的。

Basic theory of extension method is introduced in this paper.It can be applied in geological haz-ard probability of occurrence assessment.Selecting rock soil mass types,hill slope,geological structure, the number of disaster,intensity of human engineering activity and multi year average precipitation as the evaluation indexs,using the method of analytic hierarchy process for weight value,susceptibility evalua-tion model has been established based on extension theory of geological disaster.Taking Ji＇nan city as an example,the extension evaluation model is used to validate the results.The results obtained by using this method can agree with the actual situation highly.It is proved that this method is feasible.
