摘要
鉴于爆管是危及大型供水工程安全运行的严重事故工况,基于瞬变流基本理论,结合超压泄压阀的工作原理,建立了地下埋管爆管工况的水力过渡过程计算分析数学模型,并提出了供水系统中最危险的爆管位置的确定方法。实例应用结果表明,该模型能反映爆管过程中管道内压力和流量的瞬变过程,确定的爆管位置具有合理性。
Pipe burst is a serious threat to safe operation of large scale water supply project. Mathematic model of hy draulic transient is established for analysis of underground pipeline burst based on the theory of fluid transients and relief valve. And the method is proposed to determine the most danger position of pipe burst. Example results show that the transient process of pressure and discharge during pipe burst can be obtained by the model, and the choice of pipe burst point is rational.
