摘　　要：日本是世界上较早研究高速铁路隧道洞口微气压波问题以及减缓措施的国家,在新干线建设和运营过程中积累了比较丰富的工程技术经验。本文全面调研了日本新干线隧道缓冲结构设置的原则、类型,主要技术指标或参数,特别是新干线提速过程中遇到的隧道空气动力学问题和处理对策,以期对于我国400 km/h及以上高速铁路的建设提供借鉴。As one of the first countries in the world studying the micro-pressure wave at the entrance of high-speed railway tunnel and the relevent mitigation measures,Japan has accumulated rich practice and technical experience during the construction and operation of Shinkansen.In this paper,the principles,types,main technical indexes or parameters of the buffer structure of the Shinkansen tunnels are comprehensively investigated,especially the aerodynamic problems encountered in the process of speed-up of Shinkansen tunnel and the countermeasures,in order to provide a reference for the construction of 400 km/h and above high-speed railway in China.
