Research on Graded Management of Construction Risk Factors of a Subway Station

Abstract

Based on a subway station project, this paper puts forward the risk factors in the process of subway construction. The analytic hierarchy process (AHP) is used to establish the risk factor model of metro station. Establishes the risk judgment matrix at all levels by combining the results of expert investigation method. By evaluating the risk factors of the subway station, the weight values of the above risk factors are calculated and sorted. As a result, the risk management system of subway station is put forward.The research results of this method provide a theoretical basis for the project managers to determine the risk factors, and lay a foundation for the smooth progress of the subway station construction project.
