摘　　要：我国的铁路隧道比国外一些发达国家起步早很多,但是由于我国在20世纪80年代以前铁路隧道施工基本都是利用传统矿山或是整体式衬砌,加之缺少较为完善的防水设施,致使全国有将近33.3%左右的铁路隧道都有不同程度的渗漏。20世纪80年代中后期,我国的隧道施工技术有了长足进步,新奥法也在大量隧道工程中得到广泛应用,这使得隧道渗漏问题从根本上得到了改善。为了确保隧道的整体质量和行车安全,必须进一步加强隧道的防排水设计和施工质量。针对工程实际情况,提出了铁路隧道工程结构防排水的设计理念,即等级确定合理、系统构成完善和结构耐久可靠,并提出了铁路隧道工程结构防排水的有效施工措施,确保了隧道的整体质量和行车安全。China Railway Tunnel much earlier than some developed countries started,but because of our country in the last century 80＇s previous railway tunnel construction is the basic use of traditional mining and integral lining,coupled with the lack of perfect waterproof facilities,resulting in the country has nearly 33.3% of the railway tunnels were leaking.In the late nineteen eighties,tunnel construction technology in China has achieved great progress,the new Austrian tunneling method is widely used in tunnel engineering,which makes the tunnel leakage problems to be fundamentally improved.But with the rapid development of China＇s economy,railway tunnel engineering increased.In order to meet the people＇s growing travel needs and ensure tunnel overall quality and traffic safety,drainage design and construction quality control must be further strengthened tunnel.According to the actual situation of the project,the design concept of waterproofing and drainage structure of railway tunnel engineering,namely the level determined reasonable,system improvement and the structure durability and reliability,and puts forward some effective measures of waterproof and drainage construction of railway tunnel engineering,to ensure the tunnel＇s overall quality and traffic safety.
