| Abstract: |
This paper reported the design and implementation of an energy-absorption type ship collision protection device for Zhanjiang Bay Bridge in China. The main bridge is a cable stayed bridge with center span of 480m, crossing a 50,000 tonnage navigation route. The maximum possible impact force by ship to main pier is about 84MN. Due to some reasons such as limited span length, 20m deep water and soft pile ground base, it is hard to design a ship collision protection device (SCPD) for the main pier. A flexible energy-absorption SCPD was developed and applied to this bridge. This double-case self-floated SCPD consists of inner steel case, external steel case and viscous-elastic rings between them. It can reduce the maximum impact force to below 50MN, while the maximum capacity of main pier is 60MN. The capacity of this SCPD was verified by dynamic impact simulation analysis. A new 3 level protection design strategy which generated during the development of SCPD was introduced in this paper. |
