The Application of Monitoring and Measurement to Dynamic-Feedback-Design and Disease Management in Highway Tunnel

Monitoring sections were set up to track and monitor whole course for the lining wall cracks, slope sliding, tunnel deformation, twisted steel and other serious diseases in Sanggongjing-tunnel. Based on the analysis of monitoring data, the method of dynamic-feedback-design and information construction was developed to adjust and modify the design and construction program timely, and the means of back-analysis was used to calculate the internal forces of lining structures according to monitoring data. The causes for diseases were analyzed combined with all monitoring information varying with time, then, the governance measures which made it a principle to stabilize the slope and the reinforce lining at the same time were determined ultimately the principle.
