Highway tunnel damages detection and safety assessment
B Zhang · Shanxi Architecture · 2010
Through detecting tunnel lining defects,inside fracture surface outline,lining thickness,and leakiness part of back wall,combining with FLAC numerical simulation,this paper carries on security assessment on this tunnel.Results show that: although the initial completion support basically meets the stability requirements,there still exists some defects,and puts forward some proposals for tunnel maintenance management in the period of suspension,so as to ensure the tunnel safety construction.
