1 水库工程情况白沙水库始建于1951年,1956年进行了扩建加固。由于受当时各方面条件的限制,施工质量普遍较差。水库投入运用后,曾先后4次发生裂缝,前3次均为纵向裂缝,发生于1953～1957年。第4次为横向裂缝,发生于1982年。从土坝沉陷连续26a 观测资料看,大坝沉陷量大,截至1982年9月,坝顶0+925(最大坝高处)累计沉陷606mm,加上扩建前的250mm(扩建停测期间按比例加入)共856mm,占填土高度
1 Reservoir Project Baisha Reservoir was built in 1951, 1956 for expansion and reinforcement. Due to the various conditions of the time constraints, construction quality is generally poor. After the reservoir was put into operation, cracks occurred successively 4 times and the first 3 times were longitudinal cracks, which occurred from 1953 to 1957. The fourth horizontal crack occurred in 1982. According to the observation data of 26 days continuous observation of earth dam, the settlement of the dam is large. As of September 1982, the total settlement of 606 mm at the crest of 0 925 (the maximum height of the dam), together with 250 mm before the expansion Add) a total of 856mm, accounting for filling height
