摘要:
为解决深埋高铁隧道内热空气对作业人员造成的热害问题，根据能量守恒定律推导热空气在隧道内蔓延时其前锋温度随距离变化的理论模型，运用CFD软件模拟某深埋高铁隧道不同工况下沿程空气温度变化情况。研究结果表明：不通风时，热空气蔓延前锋的温度变化呈现2个明显阶段，即T>297 K时的下降极快阶段和T<297 K时的逐渐平稳阶段；及时通风能够快速降低隧道温度，推荐大小里程侧风管出口距掌子面均为45 m，通风风速分别取20，15 m/s。研究结果可为进一步优化高铁隧道通风降温方式提供参考。
Abstract:
In order to solve the problem of thermal damage caused by hot air to the operators in the deep buried high-speed railway tunnel,according to the law of conservation of energy,a theoretical model for the temperature of the front of hot air propagating in the tunnel changed with distance was derived,and the CFD software was used to simulate the air temperature change along the deep buried high-speed railway tunnel under different working conditions.The results show that when there is no ventilation,the temperature change of the propagating front of hot air presents 2 distinct phases: T>297 K,extremely fast descent phase,T<297 K,gradual stabling phase.The timely ventilation can quickly reduce the tunnel temperature,and it is recommended that both the outlet of the side duct of the large and small mileage are 45 m from the tunnel face,and the ventilation wind speed is 20 and 15 m/s,respectively.The research results can provide reference for further optimization of ventilation and cooling in high-speed railway tunnel construction.
