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