大跨公路隧道衬砌荷载确定方法的探讨

Method of Determining the Lining Load of Large Span Highway Tunnel

结合长沙市天际岭隧道工程实例,对施工监控量测资料进行了反分析,提出了大跨隧道衬砌荷载的确定方法,为类似工程条件衬砌荷载的确定提供了参考,同时,指出反分析法是确定大跨度隧道衬砌荷载的有效方法。

In order to determine lining load of large span tunnel, back analysis was carried out on the monitoring materials derived from construction measurement in Tian Jiling tunnel in Changsha city, hunan province. For results are tested to be good, back analysis is therefore an effected way to determine the lining loading of large span tunnel, which can give reference to similar engineering projects.
