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’s railway tunnel started much earlier than some developed countries abroad. However, due to the fact that the construction of railway tunnels in our country basically utilized traditional mines or monolithic linings before the 1980s, combined with the lack of more perfect water-proof facilities, there were nearly 33.3 About% of railway tunnels have different levels of leakage. In the mid and late 1980s, the tunnel construction technology in our country has made great strides, and the new Austrian law has also been widely used in a large number of tunneling projects, which has fundamentally improved the tunnel leakage problem. In order to ensure the overall quality of the tunnel and traffic safety, we must further strengthen the drainage design and construction quality of the tunnel. According to the actual situation of the project, the design concept of waterproofing and drainage of railway tunnel construction is put forward, that is, the grade is reasonable, the system structure is perfect and the structure is durable and reliable. The effective construction measures of waterproofing and drainage of railway tunnel construction are proposed to ensure the overall quality of the tunnel And driving safety.
