| Abstract: | The core idea of New Austrian Tunneling Method(NATM) considers tunnel surrounding rock and supporting structure as a whole supporting system,and monitoring measurement is the important part of NATM and rock stability.A case study of Luoping tunnel is given,based on the characteristics of burying depth and big distortion,and the contents,technique and method of monitoring in tunnel are presented.Based on the measured data,such as the ground settlement,rock deformation,bolt axial force and so on,the deformati... |
