Abstract

In order to grasp the changing regulations of circumference convergence and internal displacement of tunnel,the displacement monitoring of initial support and secondary lining is done using SW-VI convergence gauge and three-point displacement meter.The results show that the average velocity of testing sections is less than basic stabilization criterion,and reveals the working status of tunnel support structure is better.
