针对拟建的渤海海峡隧道竖井施工进行风险分析，确定了施工期间的风险并结合风险权重分析排序，依次为支护结构失效风险最小、自然灾害风险较大、竖井开挖风险最大，并通过风险评估确定了突水、突泥风险为关键风险。综合考虑关键风险与其他风险对竖井施工的影响，从地质预报、竖井吊装设备的选择与吊装过程控制、竖井开挖风险控制、自然灾害风险的预防、竖井支护结构的质量控制以及建立竖井施工作业安全制度等方面提出了对渤海海峡隧道竖井施工风险的应对措施，为后续施工提供参考。

In view of the shaft construction risk analysis of Bohai Strait tunnel, this paper determines risks during construction. Combining the risk weight analysis ranking,the sequence in turn from low to high is supporting structure failure risk, natural disaster risk and shaft excavation risk. Through risk assessment,we determine that the risk of water inrush and mud outburst is the key risk. Considering the influences of key risk and other risks on the shaft construction,we put forward response measures about shaft construction risk of Bohai Stiait tunnel from the geological forecast,shaft hoisting equipment selection and hoisting process control, shaft excavation risk control, natural disaster risk prevention, shaft supporting structure for quality control and the establishment of the shaft system construction,which provide guidance for the subsequent construction.
