Analysis of the Tunnel Construction and Monitoring Measurement under Complicated Geological Conditions

Abstract:

In view of certain areas of Guizhou are soft sandstone rock, where single block of rock's hardness is very low and easily crushed, complicated hydrogeology and low level of complex surrounding rock and geological conditions, geological radar prediction is used before the excavation of the tunnel, and New Austrian Tunneling Method was used in the construction. The process of construction segment had been monitored and measured, and the deformation of tunnel had been controlled. According to the situation during excavation and monitoring, the construction method was further improved. Through tracing and monitoring the tunnel construction of from zk40+430 to zk40+630 sections for two months, showed that the tunnel construction method is effective in this paper.
