摘　　要：针对控制排放的隧道防排水技术中一些关键问题,以龙潭隧道和白云隧道为依托,采用模型试验、数值仿真、现场调查等方法进行了系统研究。重点就堵水方式、防水板铺挂形式、外水压力的折减以及抗水压衬砌设计等技术问题进行了研究,提出了可通过注浆堵水圈、初期支护、防排水网格和抗水压衬砌形成综合防排水体系,它可以达到控制排放的目的。In order to solve some technique problems of waterproof and drainage of tunnels based on controlling drainage, model tests, numerical simulations and site investigations were performed by use of two cases Longtan Tunnel and Baiyun Tunnel. Key issues including water plugging types, waterproof board spreading methods, drop of external water pressure and lining design for resisting hydraulic pressure, etc. were studied, thus the composite waterproof and drainage system to control drainage were put forward, including grouting sphere for water plugging, primary support, grid sysytem for waterproof and drainage and lining to resist hydraulic pressure.
