摘要
以郑西客运专线阌乡隧道下穿连霍高速公路段为例,对下穿段初期支护变形规律进行了分析,提出了浅埋大断面隧道下穿高速公路段初期支护的变形控制措施,并对施工中的成功与不足进行了总结,为后续施工提供了借鉴。
Taking Zheng-Xi passenger special railway line Wenxiang tunnel underpass Lian-Huo highway as an example,the paper analyzes preliminary support deformation law,puts forward preliminary support deformation control measures of shallow tunnel underpass highway,and summarizes construction advantages and defects,which has provided some reference for continuous construction.
