| 中文摘要: |
| 文章针对重庆市某县地质环境条件、发育特征等特性,选取了地层岩性、斜坡结构类型、坡度、坡高、降雨量、结构面、人类工程活动等7个因素作为地质灾害危险性评价因子,通过层次分析法确定评价因子权重,并采用专家系统法赋值,建立了该县地质灾害危险性评价模型。通过划分评价单元及利用危险性评价模型,将该县地质灾害危险性分为危险性大区、危险性中等区和危险性小区。研究成果对相似地区地质灾害危险性的划分也提供了一定的借鉴意义。 |
| 英文摘要: |
| On the basis of the geological environment and development characteristics in a county,seven indicators for evaluating the geological disaster fatalness around the county,formation lithology,slope structure type,gradient,slope height,rainfall,structural surface and engineering activities are selected. Using the analysis hierarchy process to ascertain the weight of index,and adopting the expert system to mark for the indicators,and then,the evaluation model for the geological disaster fatalness along the county is put forward. At last,the area is divided into three risk regions:the most risk region,the medium risk region,and low risk region,and the results of the study provide some certain referential significance for similar areas. |
