扬旗山水利枢纽工程采用分期导流,一期为束窄河床导流,二期采用灌溉洞和供水洞联合导流。在高水位导流、丰水年、左右岸围堰基础无防渗的情况下进行截流,截流过程中存在诸多问题,采取有效措施后成功截流,保证了主体工程顺利实施。 Yangzishan Water Control Project uses staged diversion, one for the narrow narrow riverbed diversion, the second phase of the use of irrigation holes and water supply tunnel joint diversion. During the high water level diversion and abundant water years, there is no seepage in the left and right bank cofferdam. There are many problems in the process of river closure, and the river closure is successful after effective measures are taken to ensure the smooth implementation of the main project.
