1971年 窝水库坝体存在210余条裂缝，1985年发展到800余条，总漏水量约1149m3／d．为治理坝体渗漏，1978年前曾采用过水泥灌浆和丙凝、环氧等化学灌浆对裂缝进行过处理，同时上游面采用过环氧橡皮涂贴等处理试验，效果均不明显．1981年普查，这些裂缝不但在数量上有所增加，而
In 1971, there were more than 210 cracks in the dam reservoir. In 1985, it developed to more than 800 and the total water leakage was about 1149m3 / d. In order to control the seepage of the dam body, cracks were treated with cement grouting, polypropylene grouting, epoxy and other chemical grouting before 1978, while the upstream face was treated with epoxies such as epoxy rubber coating, the effect was not obvious. In the 1981 census, these fractures not only increased in number, but
