Abstract A framework of risk management including risk identification，estimation，evaluation and control was proposed for the safety in the whole construction process of urban tunnels with large cross-sections. Taking the North Ring Road，Jiuzhou tunnel for example，the comprehensive evaluation with fuzzy method was applied to determine the set of the levels of risk factors，the set of risk evaluation and the set of membership. The risks in the whole construction process were identified，analyzed and evaluated. The risk tracking and control are achieved with the framework of risk management proposed in the whole process of construction and avoids the weakness of the scattered，dispersed，fragmented risk management mode which was used in the previous projects.
