乌江沙沱水电站库首右岸河间地块渗漏浅析

Analyses on Seepage of Area between Rivers on The Right Bank of Reservoir Head of Shatuo Hydropower Station on Wujiang River

乌江沙沱水电站右岸河间地块可溶岩分布广泛、断裂构造发育 ,并横切贯穿河间地块形成构造缺口 ,水库蓄水后存在向车家河邻谷渗漏的可能性。本文从研究河间地块基本地质条件入手 ,运用各种勘察手段 ,对河间地块地下水运移特征及岩溶发育演变史进行初步分析 ,明确了此河间地块可能渗漏的规模及渗漏途径 。

On the area between rivers on the right bank of Shatuo Hydropower Station's reservoir,karst distributes widely,fault structures have developed and pierced through the area to form structural defects.After the reservoir forming,there is possibility of leaking from it into neighbor valley of the Chejiahe River.Studying basic geologic conditions of the area,using various investigating methods,the engineers have analyzed the features of underground water flow of the area and the karst development history,have found out the possible scale and path of seepage.The results could be as base of next research work.
