摘要
以西安地铁3号线胡家庙站—石家街站区间(ZDK33+ 116~ZDK33+ 141)工程为例,采用FLAC数值模拟与现场实测相结合的方式对大断面黄土隧道CRD(交叉中隔壁)法施工诱发的地表沉降变化进行研究.通过对监测数据的分析,得到了CRD工法施工引起的纵横向地表沉降的变化规律.该变化规律可为黄土地铁隧道施工引起的地表沉降变化及其控制技术提供参考.
Based on the section from Hujiamiao Station to Shi- jiajie Station (ZDK33 + 116~ZDIO3 + 141) on Xi'an Metro Line 3, FLAC simulation is used together with field measure- ment to study the ground surface settlement caused by CRD construction method in large cross-section loess tunnel. By ana- lyzing the monitored data, the law of longitudinal ground sur- face settlement and the transverse ground surface settlement caused by CRD construction method is detected. This research on the law will provide a reference for the ground surface set- tlement caused by the construction of loess tunnel and for the control technology at the same time.
