| 摘 要： | 利用层次分析法建立了万塘滑坡危险度评价模型，综合考虑降雨、地震、人类工程活动、库水位、地形地貌、地层岩性和岩层组合结构七个方面的因素，对三峡库区万塘滑坡进行危险度评价，并与传统的刚体极限平衡法相比较验证。通过重点定量分析降雨对万塘滑坡稳定性的影响程度，验证了降雨在滑坡稳定性中所起的关键作用，为滑坡灾害预防提供依据。

| Abstract: | The relevant model is set up in the paper for the estimation of the dangerous degree of Wantang landslide with the analytic hierar-chy process. It takes into consideration of rainfall, earthquake, engineering activities, reservoir water level, lithology and strata combination. The model is used to estimate the dangerous degree of Wantang landslide. And the result is compared with that of rigid body limit equilibrium method. With quantitative analysis of influence of rainfall on the stability of Wantang landslide, the paper verifies the key role of rainfall to the stability of landslide. It provides evidence for landslide prediction. |
