摘　　要：目前,工程企业对于隧洞、轨道交通等地下区间的废水泵站进行事故水锤校核分析较少。以南方某在建铁路隧洞斜井废水泵站为例,进行了水锤模拟与分析。针对危害较大的停泵水锤进行理论计算与软件模拟,验证了模型的准确性,通过布置进排气阀、超压泄压阀、调压塔等组合防护措施,进行了水锤模拟与分析。计算和分析过程可为其他类似工程提供参考。Currently,accidental water hammer verification analyses are rarely conducted for wastewater pump stations in tunnels and rail transit tunnels.For a wastewater pump station of an inclined shaft of a railway tunnel under construction in southern China,the water hammer simulation and analysis are conducted.Theoretical calculations and software simulations are performed for the more hazardous pump shutdown water hammer to verify the accuracy of the model.By combinations of protection measures such as intake and exhaust valves,overpressure relief valves,and pressure regulating towers,water hammer simulation and analysis are carried out.The calculation and analysis process can provide references for other similar projects.
