title: Three-Dimensional Numerical Simulation and Structural Response Dataset of UHPC-Strengthened High Pile Wharves Under Ship Impact

description: High-pile wharves are widely used in coastal port engineering due to their advantages in adapting to soft soil foundations and reducing wave reflection. However, structural damage caused by ship impacts frequently occurs, severely affecting their long-term service performance and operational safety. Existing research primarily focuses on the dynamic response and damage characteristics of high-pile wharves under ship impacts, with a lack of targeted reinforcement technology studies. Ultra-high-performance concrete (UHPC), with its exceptional strength, excellent ductility, and durability, demonstrates significant potential in structural reinforcement. To address the research gap in UHPC-reinforced high-pile wharves' resistance to ship impacts, this study systematically investigates the effectiveness of UHPC reinforcement in enhancing impact resistance through three-dimensional numerical simulation methods. The resulting dataset provides data support and technical references for the impact-resistant design and reinforcement of high-pile wharves in port engineering.Model Base Data FileThe geometric parameter files of the 3D model including the high-pile wharf, vessels, soil, and rubber fenders (such as the spacing of the wharf frame, pile dimensions, vessel length, width, and height, and the thickness of soil layers);Tables of physical and mechanical parameters for various materials (e.g., strength, elastic modulus, Poisson's ratio of concrete and UHPC, cohesion and internal friction angle of soil, Mooney-Rivlin model parameters of fenders, etc.);UHPC Reinforcement Zone Design Documents (Based on Impact Stress Concentration Zones and Damage Distribution of Unreinforced Wharves, Focusing on Beam-Column Nodes and Longitudinal Beams-Pile Connections).Structural Response Core Data FileWharf panel acceleration data: Time-history curves of acceleration for unreinforced and UHPC-reinforced wharf panels under different impact velocities, including key indicators such as peak acceleration, fluctuation amplitude, and stabilization time;Stress and Damage Data: Distribution data of maximum principal stress in the impact zone, tensile damage factor (TDF) data, covering stress concentration ranges, damage levels, and variation patterns under different working conditions;Pile response data: Pile deformation curve data (including deformation distribution of free and embedded sections), maximum displacement data at the pile head, and bending moment time-history curve data, with a focus on recording the response characteristics of the core load-bearing piles (piles near the impact point);Verification data files: Comparison data between AASHTO specifications, European unified standards, and finite element simulations of ship impact forces for model accuracy validation.
