| Abstract: | The surround stress was monitored in excavation by steel string sensor.The field monitor data were compared with numerical simulation results.The result showed that the steel string sensor can record the changing of surround rock and support stress,surround rock stress changes violent at lower bench excavation and it changed to be steady.It is instructive for the tunnel cohstruction and long-term. |
