空气动力学效应对高速铁路隧道内行车、旅客乘车舒适度、洞口环境均有不利的影响。通过对隧道内空气动力学效应的分析研究，找出解决问题的对应措施，为高速铁路隧道设计、施工、运营提供科学的理论依据。

Aerodynamic effect in a tunnel of highspeed railway can be harmful to security of train, passengers in the train and environment at entrance of tunnel. Through the study on aerodynamic effect in a tunnel, some countermeasures are proposed in this paper, which can give supports to the design, construction and operation for tunnels of highspeed railway.
