Description

一种缓解高速列车在隧道内空气动力效应的铁路隧道
技术领域
本发明涉及高速铁路隧道领域，尤其涉及一种缓解高速列车在隧道内空气动力效应的铁路隧道。
背景技术
当高速列车通过隧道时，会发生一系列空气动力效应，包括：洞内的压力突然升高，导致机车内压力发生瞬变，压力的瞬变会在人体耳膜内产生压力差，导致乘客的耳膜不适，甚至头晕、呕吐，严重影响乘客的舒适性和健康。机车、隧道衬砌结构及隧道内辅助设施（如照明灯具等）受到气动荷载的反复作用，引起车体结构、隧道内辅助设施和隧道衬砌的疲劳损伤，降低隧道内辅助设施和隧道衬砌的耐久性和使用功能，缩短隧道内辅助设施的使用寿命，甚至危及行车安全。空气阻力增大，既导致机车运行能耗增加，又导致隧道内热量积聚和温度升高，造成各种安全隐患。
发明内容
本发明要解决的技术问题是当高速列车通过隧道时，缓解洞内瞬变压力、洞口微压波效应、隧道内气动荷载、机车附加空气阻力在内的各种空气动力效应。
本发明提供的技术方案是：一种缓解高速列车在隧道内空气动力效应的铁路隧道，在隧道衬砌顶部或者两侧边设有第一井口；在无砟轨道的中间设有第二井口；在岩体与隧道衬砌之间设置通风管道，通风管道一端与第一井口连通，另一端与第二井口连通，第一井口、第二井口和风道构成了空气流通结构体；沿着隧道长度方向间隔设有空气流通结构体。
进一步地，相邻的空气流通结构体间距范围为3-7m。相邻的空气流通结构体间距范围越小，更能缓解空气动力效应，但也会导致隧道结构对岩体支撑力不强，施工成本越高，选择3-7m的间距范围可以在合理的成本下达到缓解空气动力效应的目的。
进一步地，靠近隧道洞口的空气流通结构体距离洞口10-30m。此结构能够缓解洞口微压波效应。
进一步地，第一井口的横截面为圆形，且从开口处朝内直径逐步减小。此结构有利于引导隧道内的空气顺利进入第一井口内。
进一步地，第二井口的横截面为圆形，且从开口处朝内直径逐步增大。此结构有利于从第二井口出来空气相对集中，这样能够产生较大的气压。
与现有技术相比，本发明的有益效果是：在隧道内设置空气流通结构体，当列车高速驶过时，隧道内部分空气从第一井口进入，另一部分则从隧道洞口涌出，这延长了压缩波升高到压力最大值所经历的时间，降低机车内的瞬变压力和洞口微压波峰值，从而提高乘客的舒适性，有效缓解明洞内和机车外壁的负压，从而减轻气动荷载对明洞结构及辅助设施的疲劳损伤，同时进入第一井口的空气从第二井口喷出，且喷射到列车的正下方，对列车车上产生了一个向上的推力，减轻了列车车身对无砟轨道的压力，列车的动摩擦阻力会相应减小。

其中，1、岩体 2、隧道衬砌 3、无砟轨道 4、第一井口 5、第二井口 6、通风管道。
具体实施方式
结合说明书附图，对本发明实施方式具体说明。
实施例1 一种缓解高速列车在隧道内空气动力效应的铁路隧道，其中所述铁路隧道包括岩体1、支撑岩体的隧道衬砌2和无砟轨道3，在隧道衬砌2顶部或者两侧边设有第一井口4；在无砟轨道3的中间设有第二井口5；在岩体1与隧道衬砌2之间设置通风管道6，通风管道6一端与第一井口4连通，另一端与第二井口5连通，第一井口4、第二井口5和风道6可以在隧道内同一纵截面，第一井口4、第二井口5和风道6构成了空气流通结构体；沿着隧道长度方向间隔设有空气流通结构体。相邻的空气流通结构体间距范围优选为3-7米。
实施例2 在实施例1的基础上，靠近隧道洞口的空气流通结构体距离洞口10-30m。
实施例3 在实施例1或者2的基础上，第一井口4的横截面为圆形，且从开口处朝内方向直径逐步减小。
