Collapse is an common accident during underground engineering construction. Risk analysis of collapse during construction for a metro transfer station with large span and little space is done by using theory of risk analysis,for preventing collapse accidents during construction effectively. Considering the difficulties of construction of the station,the risk assessment system is proposed. Using analytic hierarchy method to analyze the collapse risk. Then it's major risk factors and collapse risk's grade is gained,and some corresponding measures are proposed.
