Transformation Technology and Effect Evaluation of Hidden Danger of Common National and Provincial Highway Tunnels
Lu'an City,Anhui Province selected the Tongluozhai Tunnel of an ordinary national and provincial highway as a pilot project for tunnel management with typical hidden dangers.A professional safety monitoring platform integrating transportation,electromechani-cal,lighting,and ventilation was built based on BIM technology.Through dynamic analysis of tunnel environmental parameters,traffic safety indicators,and accident data,we can accurately formulate remediation plans and organize their implementation.The treatment re-sults have been remarkable:the average daily concentration of carbon monoxide in the tunnel has dropped below 80 ppm,the illumina-tion has increased to above 80 lx;the proportion of vehicles with a distance of less than 200 m has dropped to 8%,and the average an-nual accident rate has dropped to zero.
