摘　　要：从立堵截流工程实践中 ,认识到影响截流难度的主要水力因素是截流落差Z、截流流量Q和截流水深h。结合葛洲坝工程、三峡工程等截流工程简要介绍了降低以上Through the practices of the end dumping closure projects, it is recognized that the main hydraulic factors, which affect the difficulty in end dumping closure, are closure drop Z, discharge Q and water depth h. This paper introduces the main measures to lower these three factors on the basis of the end dumping closure in the Gezhouba Project, Three Gorges Project etc..

关 键 词：立堵截流 落差 流量 水深
