| Abstract: | The situation of shaped ring piece convergence and vault subsidence in a shield tunnel is monitored directly with a convergence instrument and a precise leveling instrument and the earth surface deformation by the shield-driven processing is monitored too.According to the monitoring result,we can do some analysis and judge the influence which shield driven processing effects on the earth surface subsidence.Comparing the real measured value with the initial measured value,the temporal curve on the earth surf... |
