高速铁路发展对隧道衬砌形式的影响

选取不同的隧道衬砌形式,可促使高速列车通过时产生的压力波迅速衰减,进而有效缓解高速列车通过隧道产生的空气动力学效应。从分析高速铁路隧道中的空气动力学问题及其影响因素入手,综述现有减缓措施及其弊端,提出从衬砌形式方面消减隧道中压力波的可行性;最后,对高铁隧道衬砌形式的发展方向做出合理设想,对未来高铁隧道衬砌形式的选取具有参考价值。

Effects of the Development of High - speed Railway on Tunnel Lining Styles

The various support lining styles can be applied to make pressure wave to be attenuated and to relieve the aerodynamic effects which is resulted from a moving high-speed train in the tunnel.The aerodynamic problems and its influencing factors are analyzed in the paper,the measurements and their shortcomings are reviewed and the feasibility that the pressure wave can be reduced by changing the support forms is given.Finally the development direction of high-speed railway tunnels lining style is prospected,which is significant to the selection of the lining styles for high-speed railway tunnels in the future.
