摘要
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。
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 guarantee 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 investtigation and the observations on the development of the cracks, and then puts forward prevention and treatment measures to avoid similar cracks in tunnel.
