摘　　要：抽蓄电站地下施工洞室通风质量决定洞室内产生的有毒有害气体能否有效快速排出。文章基于RNG k-ε湍流模型,建立了抽蓄电站地下施工洞室通风系统的数值计算模型,使用Fluent数值模拟软件对施工工况下的金寨抽蓄电站地下洞室全厂通风系统运行时的流体流动特性进行仿真计算。通过现场实测数据对模型可靠性进行了验证。在此基础上,针对目前的通风系统提出改进方案,并进行仿真试验,根据仿真结果给出通风改进建议,为抽蓄电站地下施工洞室的通风系统设计和安全施工提供帮助。The ventilation quality of constructing underground caverns of pumped storage stations determines whether the toxic and harmful gases produced in the caverns can be effectively and rapidly discharged. Based on the RNG k-ε turbulence model, this paper establishes a numerical model for the ventilation system of constructing caverns of pumped storage station, and the fluent numerical simulation software is used to simulate the fluid flow characteristics of ventilation system in underground cavern of Jinzhai Pumped Storage Station under construction conditions. The reliability of the model is verified by the measurement data. On this basis, the improvement schemes of the current ventilation system are proposed and simulated. According to the results, the ventilation improvement suggestions are proposed, which can help for ventilation design and safe construction of underground caverns of pumped storage stations.
