大龙潭水利枢纽地下水动态分析

Dynamic Analysis of Groundwater System of Dalongtan Project

大龙潭水利枢纽大坝基础为近于直立的层状岩体,坝体上下游为岩溶强烈发育的灰岩分布区,左右两岸岩体中分布有大量顺河向断裂,成为绕坝渗流的通道。为了监测坝址两岸蓄水前后的地下水运移状况,了解工程运行期地下渗流场的变化规律,建立了大龙潭水利枢纽大坝防渗帷幕渗流监测网。

The base of Dalongtan Project dam is almost an vertical layered rock, with overdeveloped limestone in the upper dam and lots of fractures in the flowing direction inside the rocks of both banks, which grows into damaround channels of seepage. To monitor the operation of groundwater inside both banks before and after storing water and master the changes of underground seepage field during project operation season, the anti-seepage curtain monitoring network in Dalongtan Project dam has been built.
