The Study on Gray-hierarchy Analysis in Risk Management of Subway Construction

摘要

The factors of risk management have been analyzed and evaluated in subway construction by adopting gray-hierarchy analysis. According to the characteristics of the subway construction, analyze the risk factors of the surrounding environments in the construction period, and establish the gray-hierarchy model of risk analysis. Sort the risk factors by using the gray-hierarchy analysis, and whiten gray system of engineering risk whose information are incomplete by using gray whiten weight function in gray theory. It is proved that the model is qualitative analysis by the mathematical method into quantitative analysis. Combining with the subway station engineering construction case in Xi'an, draw the evaluation value of engineering risk in subway construction.
