摘　　要：利用隧道专用软件同济曙光,对某联拱隧道施工中洞周位移进行了数值模拟和流变学分析,并与监测结果进行了比较,结果表明,该隧道在开挖46d后,其围岩已经稳定,可以依此指导隧道施工。In this paper, the numerical simulation and rheologic analysis of displacement of the surrounding rock during the twin arched-tunnel construction has been done by the dynamical FEM （GeoFBA-V3.0）, and was compared with monitoring results. The results indicated that the tunnel was stability 46 days later after tunneling construction. This analysis method and results can be used as the guidance to the construction of the tunnel.

关 键 词：联拱隧道 施工 围岩 位移
