Abstract

Chola Mountaincrossing tunnel is located in highaltitude area (higher than 4 000 m); and it is constructed by drilling and blasting method. The harmful gas monitoring results show that the carbon monoxide (CO) content can not meet the requirements of related criteria. Comparison is made among the variation of CO induced by drilling and blasting, that exhausted by diesel engine and that in tunnel; and the results show that CO exhausted by diesel engine is the main source. Finally, related countermeasures are proposed.

Key words： tunnel in highaltitude area; air quality; diesel engine; carbon monoxide (CO); harmful exhaust purifying
