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.
