1 引言水工建筑物是用来控制水流、利用水资源为人类服务的工程设施,而闸门则是其中用来凋节、控制水流的主要设备。在一座水工建筑物上至少设置有一套闸门,一座大型水利枢纽工程上(如葛洲坝水利枢纽、三峡水利枢纽等)往往设置有许多各种类型的闸门,以满足水工建筑物控制水流的各种需要。闸门工作的好坏将直接影响到水工建筑物的正常运行、国家财产和人民群众生命的安全,因此它是水工建筑物的一个重要组成部分。
1 Introduction Hydraulic structures are used to control water flow, use of water resources for human services engineering facilities, and the gate is one of the main equipment used to witness, control of water flow. There is at least one set of gates on a hydraulic structure. For a large-scale water-control project (such as Gezhouba Dam and the Three Gorges Dam, etc.), there are often many types of gates to meet the requirements of each Kind of need. Good and bad gate work will directly affect the normal operation of hydraulic structures, national assets and the safety of people’s lives, so it is an important part of hydraulic structures.
