Abstract
Based on measured data of Wuxinzhai tunnel in expressway of Shanyin to Pinglu, mathematical methods were used to make regressing analysis of measured date on crown settlement and periphery convergence. According to the time-effect of soil mass excavation in New Austrian Tunneling Method, the relations between rock deformation and time during the tunnel construction was analyzed. The results of analysis could provide an theoretical basis for modifying design and construction , and also could offer an example for similar projects in this area.
