Although more and more research achievements have been obtained in offshore engineering in recent years, there are few studies on transportation of bridge under marine condition. In order to explore the response characteristics of bridge transportation under the action of marine environment, this paper conducts numerical simulation of the transportation of a butterfly arch bridge by a semi-submersible barge. In this paper, the software based on potential theory has been used to analyze the swing motion of the transportation of bridge. The motion response of the combined float has been calculated under the action of wind, waves and currents with the varying of frequencies and directions. The results show that the swing motion amplitude of the combined float in the condition determined by the local code is relatively small, and the action of waves are the main factor of the swing motion compared to wind and currents. |
