四川某水电站库区浸没问题预测

Submergence Forecasting of a Reservoir Area in Sichuan

水库蓄水后 ,库水对地下水的顶托作用使地下水壅高超过临界而出现浸没问题。在分析库区工程地质条件的基础上 ,确定地下水临界埋深 ;并建立浸没计算模型 ,计算可能浸没的范围以及浸没相对于水库蓄水位的滞后时间 ;最后针对不同的浸没类型提出浸没防护措施 ,这将有利于库区地质环境保护和可持续发展。

With the rising of the reservoir water level gradually,the groundwater in two banks will be jacked up to rise accordingly,causing the submergence of farm and villages.On the basis of analysing the geological condition of reservoir area, the depth of groundwater buried is determined and the possible submergence range and the submergence time lagging behind are determined through calculation. At last, some effective measures of preventing submergence are put up,which will facilitate the geological environmental protection and sustainable development of reservoir area.
