摘要
连拱隧道结构复杂,施工工序繁琐,施工期围岩稳定是关系到隧道安全施工的关键问题。结合下杨干双连拱隧道施工期围岩变形与结构受力监测,分析下杨干连拱隧道施工期结构受力与围岩稳定性情况,可供类似工程参考和借鉴。
Stabilization of surrounding rock is the key to construction safety for multi-arch tunnel because of its complicated structure and construction procedure.Stability of surrounding rock and structure stress are analyzed combined with deformation and structure stress monitoring of Xiayanggan Multi-Arch Tunnel during its construction period,which can present reference for other similar engineering projects.
