| 摘 要： | 乌鞘岭隧道是兰新线重点控制工程,是国内最长的单线铁路隧道。该隧道穿越四条区域性大断层,地应力高,围岩软弱、破碎,隧道变形大。针对高应力条件下的软岩隧道大变形特点,在F4~F7断层区段,开展了系统、全面监控量测。根据实测数据,深入分析了支护压力、支护应力的规律及特征,及时将信息反馈给设计与施工,为工程施工提供了主要的技术支持。

| Abstract: | Wushaoling railway tunnel is the longest single-track railway tunnel in China and is the key project of Lanxin railway line.It goes through four regional faults(F4~F7),with complicated geological and geostress conditions.According to the large deformation characteristics of soft rock tunnel in the complicated stress condition,a comprehensive monitoring was executed during the construction of Wushaoling tunnel.Based on the measured results,the rules and characteristics of pressure and stress were analyzed and the information was fed back in time to provide the basis for the tunnel construction. |

| Keywords: | Wushaoling tunnel monitoring the surrounding rock pressure support stress |
