摘　　要：　模拟水锤波速是有压引水系统水力过渡过程水工模型试验的技术关键之一。本文对控制模型试验中水锤波速的几种方法进行讨论分析,在此基础上提出在模型管道中放置高弹性细管以降低波速的方法,并指出应该进一步通过模型试验研究此种方法的机理和各相关因素对波速的影响,以提供一种更有效的降低模型管道中水锤波速的方法。Controlling the water hammer wave velocity plays a key role in model test to simulate the water hammer velocity. In this article several methods of controlling the water hammer wave velocity are analyzed. A method of controlling the water hammer wave velocity is introduced by setting thin sliding pipes in the pipelines. An opinion is pointed that further model tests should be carried on to investigate the theory of this new method and the effect of various factors on water hammer wave velocity in order to provide a more effective method of controlling the water hammer wave velocity.
