| 摘 要： | IntroductionThe micro pressure waves generated by high- speedtrains entering tunnels have caused manyenvironmental problems in recent years. Manystudies have been carried outon the generation andpropagation of micro pressure waves. When alocomotive enters the tunnel,a compression waveis formed,distorting and attenuating as itpropagates with the speed of sound.If the tunnelis a slab track tunnel and is long enough,the wavewill eventually form a weak shock wave. Theemission of the shock wave fr…
