The maximum reaction force of the rubber fender selected by the ship impact energy is generally used as the design load in the energy dissipation system of the pole of high-tonnage floating wharf,which meets the engineering needs,but is not economical.The motion state of a pontoon after being hit by a ship is analyzed,and the maximum impact energy of the barge’s first impact on the pole is used as the design basis for the pole system.By studying the relationship between energy absorption of fender,energy absorption of pile foundation and fender reaction,the influences of cantilever length of pile foundation,pile diameter and fender selection on energy absorption ratio of rubber fender and fender reaction are revealed.The results indicate that rubber fenders play a major role in energy dissipation systems,with energy absorption accounting for typically over 90%.As the cantilever length of the pile foundation increases,the proportion of energy absorbed by the rubber fender decreases,and the fender reaction force also decreases.As the pile diameter increases,the proportion of energy absorbed by the rubber fender increases,and the fender reaction force also increases,but the impact is relatively small.As the size of the fender increases,the proportion of energy absorbed by the rubber fender slightly decreases,and the fender reaction force significantly increases.
