摘要
金安桥工程实施截流时只有1号导流洞单洞导流,截流流量为829m3/s,最大落差4.72m,最大流速达7.15m/s,截流段河床地形、地质条件复杂,在截流模型试验成果基础上对截流过程中可能出现的困难进行了分析,按确定方案实施了截流,顺利实现了大江截流。
During river closure of the Jinanqiao Project, only No. 1 diversion channel was used for water diversion. The closure discharge was 829m^3/s, the maximum water head was 4.72m, and the maximum speed was 7.15m/s. The landform of riverbed in the section of river closure and geological conditions was complicated. Thus possible difficulties with river closure were examined on the basis of experiment results of river closure model. River closure was successfully completed according to the proposed plan.
