摘要
建立了长距离重力输水管道中的水锤边界条件方程式和水锤暂态压力模型,利用计算机模拟分析了长距离重力输水管道在非正常关阀情况下的水锤压力,提出了水锤防护措施,并结合实际工程案例,对多种常见的长距离重力输水管道水锤防护方案进行了对比研究。
The water hammer boundary condition equations and the transient pressure model for long distance gravity water transfer projects were established. The water hammer pressure under the conditions of abnormal valve closing in long distance gravity water transfer pipelines was analyzed by computer simulation and measures for water hammer control were put forward. The comparison was made for the schemes of water hammer control in long distance gravity water transfer pipelines combining with practical project cases.
