In view of the first use of an integrated ship for floating installation of immersed tubes,it is not possible to directly measure the force on the buttress at the ship-pipe connection,and there is no relevant engineering experience for reference.This paper uses numerical simulation analysis of buttress forces to determine stress characteristic points during immersed tubes transportation,establishes a relationship between vertical and horizontal pressures of buttresses and stress at characteristic points,and proposes a new method for measuring forces on ship-pipe connections.The study shows that during the process of using an integrated ship to transport immersed tubes,the vertical pressure on the bow buttresses gradually increases while there is a slight decrease in vertical pressure on mid-ship buttresses;there is little change in vertical pressure on stern buttresses.Horizontal pressure on buttresses is positively correlated with speed;during high-speed travel,there is consistently greater force exerted in the horizontal direction.When decelerating,inertia forces mainly affect the buttresses causing changes in force direction which require attention.
