摘要
高速列车通过隧道时会在隧道内引起瞬变压力、在隧道出口形成微气压波.微气压波会对隧道出口的周边环境和周围建筑物造成危害,采用帽檐斜切式洞门可大大消减微气压波的影响.本文对斜切式洞门的结构型式、结构设计及斜切式洞门对微气压波的消减效果等进行了研究,可供类似工程参考.
The transient pressure will be created in tunnel when high-speed train passes through the tunnel, which can also generate micro air pressure wave in tunnel exit. Micro air pressure wave is harmful to the environment and structures around the tunnel exit, while the tunnel portal with hatbrim slanting cut method can reduce the influence greatly. Based on the tunnel portal with hat-brim slanting-cut method, the structural style, structure design and reduction effect of tunnel portal with slanting-cut method on micro-pressure wave, etc. are studied systematically in this paper, which can be references to similar engineering projects.
