摘　　要：我国部分高铁站房虹吸雨水检查井出现了在暴雨情况下井盖“起舞”现象,存在严重安全隐患。为了解决此问题,通过对我国数个高铁站房消能井存在问题的调研,以及现行规程对消能井做法要求的研究,以计算机模拟计算(CFD)技术为载体,数值模拟了某站房虹吸雨水消能井井盖的压力变化情况,分析了消能井排气措施对消能井井盖压力的影响。模拟结果表明:当暴雨强度较大时,虹吸雨水出户管内夹杂大量的空气,如果消能井未采取排气措施,空气会滞留在消能井内部,造成井盖承受压力增大,存在井盖掀翻风险;在消能井采取排气措施后,井盖所受气压减小,井盖掀翻风险可以消除。In certain siphon rainwater inspection wells at high speed railway(HSR)station buildings in China,the covers tend to“dance”during heavy rainfall,leading to significant safety hazards.To address this issue,an investigation was conducted into the problems existing in energy dissipation wells at several HSR station buildings in China.Additionally,construction requirements for energy dissipation wells outlined in current standards were examined.Numerical simulation was conducted using CFD technology to analyze the pressure fluctuations experienced by the covers of siphon rainwater energy dissipation wells within a station building.Furthermore,the influence of air vent measures for energy dissipation wells on the pressure exerted on their covers was analyzed.The simulation results indicate that during intense rainstorms,there is a significant volume of air within the siphon rainwater outlet pipe.Without implementing vent measures for energy dissipation wells,the air accumulates inside,elevating the pressure on well covers and leading to a cover overturning risk.Upon integrating vent measures for energy dissipation wells,the pressure on well covers diminishes,consequently eliminating the risk of cover overturning.
