摘　　要：根据三维不可压缩Navier-Stokes方程和标准k-ε湍流模型,以我国高速铁路普遍采用的100m2双线隧道为研究对象,对高速列车在隧道内运行时列车风的变化规律和分布特征进行了深入研究,计算隧道内两侧疏散通道上不同位置在列车运行过程中的最大风速,进一步分析在列车风作用下人员的安全性.研究表明:列车风是随时间和空间而变的复杂三维流动,人员应避免在危险时段活动,单车正常运行和存在列车事故时列车风均有可能对人员造成安全威胁,需采取相关措施避免事故发生.According to the three-dimensional incompressible Navier-Stokes equations and the standard turbu- lence model, the 100 double-line tunnel cross-section which is generally used in high-speed railway of China is studied, this paper has made a thorough study on the variation rules and distribution characteristics of train wind, and has calculated the maximum wind speed at different positions on the two evacuation passageways, at the same time the influence that train wind on personnel safety is further discussed. The results show that： Train wind is complex three-dimensional flow which is changed with time and space, person should avoid ac- tivities at dangerous time, personnel safety may be threatened by train wind on two train driving conditions： one is that a single train runs through tunnel normally while the other is that another train runs beside a train parked in the tunnel. Corresponding measures should be taken to avoid accidents.
