摘　　要：塌方是地下工程施工中常见事故,为有效预防施工阶段塌方事故的发生,运用风险分析理论对某大跨小净距地铁换乘站施工阶段塌方风险进行研究,考虑其施工难点,建立施工阶段塌方风险评估指标体系。采用层次分析法(AHP)进行计算分析,得出主要风险因素和塌方风险等级,提出应对措施。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.
