建国以来,我国共修建了四千多座隧道,总延长二千余公里,取得了很大成绩,积累了一定的经验。但是,目前约有三分之一的隧道有不同程度的漏水,严重地损坏了隧道内部设备,影响线路通过能力,危及行车安全。还有许多隧道待查。因此,隧道漏水是急待解决的问题。 Since the founding of the People’s Republic, a total of more than 4,000 tunnels have been constructed in our country, with a total extension of 2,000 kilometers. Great achievements have been made and a certain amount of experience has been accumulated. However, about one third of the tunnels currently have some degree of water leakage, seriously damaging the internal equipment of the tunnel, affecting the passage capacity of the tunnel and endangering traffic safety. There are many tunnels to be investigated. Therefore, the tunnel leakage is an urgent problem to be solved.
