Study on the threshold of CO pollution emission concentration in Road Tunnels of the Dayou Mountain and Laji Mountain in Qinghai Province
In order to determine the CO threshold of emission concentration during the operation period of the Dayoushan and Lajishan highway tunnels in Qinghai Province,collect the relevant rules of Pollutant emissions in highway tunnels at home and abroad,and carry out the CO design concentrations,calculation models and calcula-tion methods in the tunnel design specifications at home and abroad,it is found that the calculated values as CO threshold value are too large to suitable,finally 70 ppm is determined as the threshold value of the control CO con-centration of the Dayoushan and Lajishan highway tunnels in Qinghai Province.
