摘　　要：针对山地岩溶城市高水压暗挖轨道交通车站隧道,在总结我国矿山法隧道防排水型式的基础上,对衬砌结构水压力分布特征和水压力计算方法进行了重点探讨,以期能够兼顾地表生态环境保护和隧道衬砌结构设计优化。以某城市轨道交通车站为工程实例,计算分析了“全封堵型”隧道和“堵排结合型”隧道对应的衬砌结构力学性能,研究成果可为类似隧道工程的设计提供借鉴参考。Aiming at the high water pressure underground excavation of rail transit station tunnels in mountainous Karst cities,on the basis of summarizing the waterproof and drainage types of mining tunnels in China,the water pressure distribution characteristics and water pressure calculation methods of lining structure are mainly discussed,in order to give consideration to the protection of surface ecological environment and the optimization of tunnel lining structure design.Taking an urban rail transit station as an engineering example,it calculates & analyzes the mechanical properties of the lining structure corresponding to the full plugging tunnel and the plugging & drainage combination tunnel.The research results can provide references for the design of similar tunnel projects.
