1 综述巴家嘴水库位于黄河中游支流泾河上游蒲河上,大坝为黄土均质坝。1958年建库以来经两次加高,现有坝高74m,库容5.11亿m~3。由于大坝填筑质量差,裂缝不断;泄洪能力小,滞洪时间长,水库淤积严重,一直列为全国病险库。大坝经1980、1984年两次全面灌浆加固处理,质量有明显改善。1992年再度出现险情并开工增建泄洪洞工程,1999年5月基本竣工。
1 Overview Bazijia reservoir is located in the upstream of the upper reaches of the Yellow River tributary of the Pu River, the dam is loess homogeneous dam. Since its establishment in 1958, the dam has been twice raised in height and the existing dam height is 74m with a storage capacity of 511 million m 3. Due to the poor quality of dam filling, cracks continue; flood discharge capacity is small, a long time detention, reservoir siltation serious, has been listed as a national risk base. The dam was fully grouted and reinforced twice in 1980 and 1984, and the quality of the dam has been significantly improved. Again in 1992 and the danger began to build additional flood discharge tunnel project, basically completed in May 1999.
