摘要
水库塌岸是三峡库区重大地质灾害之一。通过三峡库区数百段库岸的塌岸地质现场调查和预测分析的基础上,提出了类似三峡这种山区河道型水库的塌岸预测新方法——岸坡结构法(RBSM),并给出了详细的图解方法和预测步骤。同时,开展了二滩、宝珠寺和龚咀三个运行中的类比水库和三峡水库(139m蓄水)的塌岸预测检验,验证结果表明该方法适宜于三峡水库以及类似的山区河道型水库塌岸预测,从而为水库塌岸预测与防治工程提供重要依据。
Reservoir bank-collapse is one of the most severe geological disasters in the Three Gorges Reservoir area.Based on survey and analysis of geological conditions in several hundred river bank districts of the Three Gorges Reservoir, a new method of reservoir bank-collapse, River Bank Structure Method （RBSM）, is introduced and presents its examples of detailed determination and operation steps in this paper. The validity and reliability are proved by some bank-collapse prediction in the Three Gorges Reservoir and other reservoirs （Ertan, Baozhusi and Gongzui）. And it has been successfully applied in the Three Gorges Reservoir as an important reference for designing of bank-collapse control engineering.
