高速列车隧道压力舒适度及安全性研究

Study on Pressure Comfort and Safety in High-speed Trains Tunnels

对比国内外高速列车压力舒适度标准，提出适用于200～250km／h车速范围内列车的压力舒适度指标。基于一维流动理论，建立含车站及风井的隧道模型，针对不同的列车运行速度以及密封性指数，对车内的压力变化进行模拟分析，并考虑当列车密封性指标下降或不密封时，车内人员的压力安全性指标。

Contrast to the standard of pressure comfort in high-speed train between domestic and foreign, the level of pressure comfort is given in the range of 200-250 km/h train speed. A tunnel model with shafts and station was established based on one-dimensional theory in this paper, and the influence on pressure change inside the train was analyzed according to the different train speed and air-tightness index, and the pressure safety of personnel inside the train was considered when the air-tighmess of the train was declined or invalided.
