Deformation monitoring and numerical simulation of shallowly-buried long-span double-arch tunnel

YUE Shun,DAI Gao-fei,PI Wen-li(College of Resource and Environmental Sciences,Chongqing University,Chongqing 400030,P.R.China)  
Monitoring and measuring of new Austrian tunnelling method(NATM) was conducted with a Leica TCA2003 Total Station and an XP99 Cymometer in a shallowly-buried long-span tunnel.The deformation and movement of country rock in tunnel were obtained to guide tunnel construction.Based on the country rock deformation,the optimum time for primary and permanent support was applied.Optimum timing successfully can avert accidents in construction and enhance construction quality.Numerical simulation indicates that tunnel excavation may have great influence on surrounding rock stability.It is important to reinforce monitoring to relevant locations during the construction process,to have timely feedback to guide construction,to adopt corresponding shoring measures,and to ensure construction safety.
