Abstract:

Tunnel section installation vessel is a special engineering ship which is used in tunnel section installation under the water. During the transportation, the vessel needs to be tied with the tunnel sections so as to decrease the impact of current force and save the site connection time. According to the structural characteristics of tunnel sections and installation vessel, a reliable method is designed. The method is verified through checking calculation. It can provide certain reference for the engineering staff.

Key words: engineering ship, tunnel section installation vessel, underwater tunnel section, colligation during floating transportation, the Hong Kong-Zhuhai-Macao tunnel
