Analysis on Displacement Monitoring in Tunnel Engineering

Xue Qing Jing

Abstract

Displacement monitoring is an important component of New Austrian Method in tunnel engineering.Analysis of monitoring information and state judgment of surrounding rock and supporting structure are very important to optimization design and construction safety.The displacement convergence was monitored in the tunnel of Anji Mountain to acquaint the change of surrounding rock after excavation and forecast danger in time.The stability of surrounding rock can be judged by analysis on characteristic of velocity curve in displacement convergence.It can also provide evidence for construction time of secondary lining.
