摘　　要：以钱江特大盾构隧道为背景,对盾构推进段施工过程中的风险点进行辨识,探讨了各项风险的发生机理,并采用同济大学开发的盾构隧道施工风险管理与控制软件(TRM1.0),对调研数据进行了计算分析以评定风险等级,最后结合分部工程分析给出了风险控制措施以及相应的结论和建议。With the background of the very large shield tunnel across Qiantang river in Zhejiang Province,this paper identifies the risks of shield excavation and studies their cause in detail.The risk assessment and its rank were finished by using the Risk Management Software(TRM 1.0)to calculate the inquisitional data from many experts. Finally,some measures to reduce or control the risk loss are given,and some conclusions and suggestions were pro- posed here.
