Abstract:Pile-supported wharves are increasingly utilized in practical engineering due to their numerous advantages.The mooring force of a ship is a critical parameter in the structural design of pile-supported wharves.According to the JTS 167-2018 Design Code for Wharf Structures, the transverse component of the mooring force is distributed to the frame bent based on specific coefficients.However,the mooring force is a three-dimensional resultant force in the actual engineering encompassing lateral,longitudinal,and vertical components in reality,rather than a single lateral horizontal force.On the basis of a practical design case of a pile-supported beam-slab wharf, we apply Yigong and ROBOT software,conduct a comparative analysis of ship mooring force distribution coefficients of 2D and 3D models aiming at framed bent of the pile-supported beam-slab wharf,and provide recommendations for the practical engineering design.The results indicate that under the proposed conditions,the distribution coefficients specified in the design code underestimate the values.The calculation method of the Yigong 2D model processes vertical forces using horizontal distribution coefficients and neglects the effects of longitudinal forces,potentially underestimating the impact of mooring forces.
