在铁路隧道的施工中,二次衬砌出现裂缝已越发频繁,严重威胁着铁路的质量和安全,对于铁路的运营埋下了不可估量的隐患.为了保证铁路隧道的施工质量,外观形象,结构安全,本文以四川兰渝线某隧道为例,对其二次衬砌产生的裂缝进行定性分析,对裂缝的发育情况进行了进一步的观测排查,进而对铁路隧道二衬的裂缝提出了预防及处理措施,使得隧道以后避免出现类似的裂缝.
在鐵路隧道的施工中,二次襯砌齣現裂縫已越髮頻繁,嚴重威脅著鐵路的質量和安全,對于鐵路的運營埋下瞭不可估量的隱患.為瞭保證鐵路隧道的施工質量,外觀形象,結構安全,本文以四川蘭渝線某隧道為例,對其二次襯砌產生的裂縫進行定性分析,對裂縫的髮育情況進行瞭進一步的觀測排查,進而對鐵路隧道二襯的裂縫提齣瞭預防及處理措施,使得隧道以後避免齣現類似的裂縫.

In the construction of the railway tunnel, the seco-ndary lining cracks have become more frequent and serious, which threat to the quality and safety of the railway, and buried incalculable risks for the railway operators.In order to guarant-ee the quality of the construction ,the appearance and structural safety of the railway tunnel,taking the Lanzhou-Chongqing line in a tunnel for example, this paper makes a qualitative analysis of its secondary lining cracks,and makes further inv-est igation and the observations on the development of the cracks, and then puts forward prevention and treatment measu-res to avoid similar cracks in tunnel.
