Abstract
The ocean plays a crucial role on Earth by providing essential ecosystem services and resources. In response to the complex and dynamic marine environment, studying the interaction between waves and nearshore engineering structures has become increasingly important. This paper employs an improved Smoothed Particle Hydrodynamics (SPH) method to investigate the hydrodynamic characteristics of double wave-dissipation chamber perforated caissons, with a focus on their wave-dissipation performance and load-bearing capacity. The study explores the impact of various parameters, including relative width, water depth, and perforation ratio, on the caisson’s total horizontal force and reflection coefficient. The findings reveal significant linear and nonlinear relationships between these factors and the caisson’s hydrodynamic properties, supported by well-matched fitting formulas. The results offer valuable insights for optimizing perforated caisson designs to enhance wave-dissipation capabilities and structural efficiency, providing a solid theoretical foundation and practical guidance for coastal engineering applications.
