Study on risk management of floating transportation and installation operation of immersed tunnel based on ShenZhong Link

Abstract

In the construction process of immersed tunnel, the construction technologies of floating, mooring, sinking and docking are complex, the safety risk of construction operation is high, and the construction management is difficult. In order to reduce the safety risks in the construction process, managers need to carry out risk management. In order to better carry out risk management of this project, this paper proposes to establish a whole staff participation, whole process and dynamic database of risk management, through the risk database management and application, and then to achieve effective risk management, so that construction safety risk of this project can be at an acceptable level. The database includes risk identification, risk source classification, risk analysis, risk assessment, risk disposal and summary review.
