Abstract
In order to guarantee the construction quality and personnel safety during the subway construction process, the index system of subway construction safety management factors was established on the basis of questionnaire survey and factor analysis, including a total of 20 items. Introduce a pessimistic coefficient to optimize the hierarchical analysis model of interval numbers, construct a reciprocal judgment matrix of interval numbers that meet the requirements of consistency approximation, give weight to various safety management indicators during subway construction, improve the scientificity of weight setting, and make The key points and difficulties of construction safety management work provide a basis for ensuring the safety of subway construction.
