| 岩溶塌陷是多因素相互影响，成因机制较为复杂的地质灾害类型，在空间上具有隐蔽性，时间上具有突发性的特征。为有效预测、评价岩溶塌陷危险性，本文采用GRA -FAHP，从岩溶条件、覆盖层条件、地下水条件、工程活动条件等因素出发，选取14个主要影响指标构建定性与定量相结合的岩溶塌陷危险性评价模型，以贵州省独山县交摆村岩溶塌陷区为例对模型进行验证。结果表明，该模型对岩溶塌陷危险性评价与实际情况相符。可为今后岩溶塌陷危险性的预测、评价提供一些借鉴。 |

| Karst collapse is a geologic hazard caused by many factors and of complex genetic mechanism, it present concealment in space and burstiness in time respectively. In order to predict and assess the risk of karst collapse effectively, in this paper, according to the conditions such as karst, covering, groundwater and engineering activities, 14 main influence indexes has been chose to construct the quantitative and qualitative the karst collapse risk assessment model by the means of Grey Relational Analysis (GRA)-Fuzzy Analytic Hierarchy Process(FAHP). And the case of karst collapse area at Jiaobai village in Dushan county has been taken to validate the model. The results showed that the assessment on karst collapse was consistent with the actual situation. It provide some reference for the future risk prediction and assessment on karst collapse. |
