Experimental study on mooring, towing and installing of immersed tunnel caissons

Mooring,towing and installing tests on immersed tunnel caissons across the Yong River are carried out in basin to investigate the motions and line tensions.In the towing operation,the maximum tension exists in the case that half caisson is exposed to waves and currents.The cooperation of operating manually on many lines at the same time is very difficult and important.The dynamic behavior of the caisson and the line tensions are affected more by the manual operations than by waves and currents.In the instal...
