With the increasing number of subway lines and subway workers, their occupational health risks should be paid attention to. As the workplace, operation content, operation time, operation frequency and operators of metro operation and maintenance posts are determined according to the actual needs, the type, concentration or intensity, number of people, time and frequency of occupational hazards factors exposed are uncertain, and the risk is in a gray state, so it is difficult to evaluate their occupational health risk by quantitative evaluation method. Therefore, this paper takes a maintenance operation of Xi’an subway as the research object. The occupational health risk AHP model of subway maintenance operation was established from four aspects, which were occupational hazard factors, environmental factors, human-computer interaction factors and management factors. The gray analysis method was used to evaluate its uncertain risk. The comprehensive risk assessment results of occupational health for subway maintenance workers is between low and low risk level, which shown that the grey AHP can be used in the occupational health risk assessment of subway maintenance workers.
