Abstract:The existing safety risk identification methods of subway tunnel construction lack certain systematicness,and lack multiimensional risk scenario identification in the risk identification process, so they have certain limitation. Based on the hierarchical holographic modeling (HHM) method,risk filtering,ranking and management(RFRM)framework and scenario analysis theory,a HHM method for identifying risk scenarios in subway tunnel construction was constructed. The risk scenarios were identified from multiple perspectives, and were filtered and sorted by the RFRM framework four-times to screen the keyrisk scenarios. The case study of a subway tunnel project in C City shows that the method can systematically and perfectly identify the safety risk scenarios and keyrisk factors of subway tunnel construction, and further layscertain foundation for risk management.
