摘要
长洲水利枢纽坝址区的两个江心岛泗化洲岛和长洲岛将浔江隔成三江,对任何一江截流,其他两江的流量过程均是非恒定的。这种非恒定流过程对截流时通航水流条件和截流龙口水流条件均产生了进一步的恶化,较大地增加了截流难度。截流试验研究所阐述的现象和问题,在实际截流时得到了较好的再现;所给出的解决方案和工程措施,有效地保证了实际截流工作的顺利完成。
The Xunjiang River is divided into three parts by Sihuazhou Island and Changzhou Island in Changzhou Hydraulic Complex,and the flow will become unsteady when anyone of them is closed.This unsteady flow would make it more difficult to close the river due to further deterioration of flow conditions for navigation caused by river closure.Phenomenon and problems in river closure experiment are all found in the practice,and solutions and engineering measures proposed in this experiment make river enclosure complete successfully.
