钢管振动问题,过去设计时不作考虑。在实践中,不少水利水电工程的压力引水钢管,曾发生过不同程度的振动,国外也不乏实例,直接影响了水电站的正常运行,迫使设计者不得不加以研究。但由于振动是一个非常复杂的问题,目前仍依靠实践经验建立起来的经验公式,对可能发生的振动进行估计和作为已经发生振动的钢管拟定处理措施的依据。 Steel pipe vibration problems, the past design without consideration. In practice, many water and hydropower projects have diversion pipelines. There have been various degrees of vibration. There are also many foreign examples that directly affect the normal operation of hydropower stations, forcing designers to study them. However, since vibration is a very complicated issue, empirical formulas based on practical experience are still being used to estimate the possible vibration and to form the basis for the treatment measures for the steel pipe that has vibrated.
