Displacement Measurement and Stability Analysis of Wall Rock in Cave Depot Excavation under Complicated Geological Conditions
Monitoring and measurement to the stress adjustment and deformation of wall rock are necessary procedures in the design and construction of underground engineering when using new Austrian tunneling method (NATM). It is very important for us to monitor the deformation of wall rock in the course of tunnel excavation in the middle of strong efflorescence, frozen entirely and cracked stratum in the west. In this paper, according to the actual traits of the engineering, the problem of the information construction monitoring of the tunnel is studied under the condition of complicated geology and analyzed monitoring results of deformation of wall rock, the engineers can obtain feedback on the deformation of wall rock and supervise construction, thereby the safety of tunnel is guaranteed surly during excavation. The achieved results can provide references to the information construction engineering practice.
