摘要
海底沟岩溶地下水库建造在川东平行岭谷区带条状背斜山腹内,是以石灰岩和白云岩岩层以及石膏矿层的溶洞通道为主要储水空间的地下水库。库容加23万m^3,正常水压85～90万Pa,库区面积约12km^2。它系堵塞江北煤矿平硐一突水点而成,水库造价35万元,自七十年代末期建成以来,灌面逐年扩大至20000余亩,具良好的经济效益、社会效益和环境-生态效益。研究其岩溶发育规律和地下水库成库条件,对开发川东褶皱带岩溶水具有重要意义。
The Haidigou subterranern reservoir is the earliest one built in parallel ridge and valley karst area, 30km to the northeast of Chongqing, Sichuan, which is a buried karst underlain by clastic rock bed(T3xj). The buried karst limestone ( T2l+T1 j) intercalated with gypsum beds make up the core of an anticline.
The subterranean reservoir was formed by blocking water invasion point in a transport tunnel of the Jiangbei coalmine. The huge caverns and passages ( underground river) develop in the anticlinal mountain. The storage of the reservoir is about 20.23 millions cubic metres and the water pressure 85～90 barometric. It can supply 3.4 millions cubic metres water to irrigate 20 thousands mu farmland every year. The construction costs 350 thousands yuan, which is less than the same on the surface.
