摘　　要：【目的】廊涿干渠工程自试运行以来,经历了2次爆管过程。为了保证廊涿干渠正常输水,需采取降压运行和工程加固措施,将原设计下调节方式优化为中控制下调节方式,并在管道末端设置调压塔。【方法】本研究通过建立输水管道系统模型,对管道各种运行调节工况进行模拟计算,以验证新调节方式和调压塔的有效性和安全性。【结果】通过计算,确定了调流调压阀、调压塔的操作规程等设计参数。【结论】结合廊涿干渠实际运行情况,验证了降压运行和工程措施的有效性,保证了管道系统的安全。[Purposes]Since the trial operation of Langzhuo main canal project,it has experienced two bursts.In order to ensure the normal water delivery of Langzhuo main canal,it is necessary to take de⁃pressurization operation and engineering reinforcement measures,optimize the original design adjust⁃ment mode to the medium control adjustment mode,and set up a pressure regulating tower at the end of the pipeline.[Methods]In this study,a water pipeline system model was established to simulate various operating conditions of the pipeline to verify the effectiveness and safety of the new regulation method and the surge tower.[Findings]Through calculation,the design parameters such as flow regulating valve and operation rules of pressure regulating tower were determined.[Conclusions]Combined with the ac⁃tual operation of Langzhuo main canal,the effectiveness of depressurization operation and engineering measures is verified,and the safety of pipeline system is ensured.
