The swift advancement of underwater weaponry has thrust deep water explosions into the spotlight as a strategic asset. This study endeavors to delve into the load dynamics of deep water explosions in proximity to curved boundaries, elucidating the behaviors of shock waves, bubble movement, and jet load transmission. Employing the structured arbitrary Lagrangian–Eulerian method, we construct a coupled fluid–structure interaction model to replicate the propagation of loads during deep water explosions. Subsequently, we examine the dynamic behavior of bubbles generated by deep-water explosions near curved boundaries, elucidating the impact of water depth and detonation distance on their non-spherical motion. Finally, we consolidate the load patterns of bubble jets near curved boundaries across diverse scenarios. Our findings reveal that deep-water explosion loads are affected by variables including water depth, detonation distance, and boundary conditions, displaying a discernible pattern and complexity. The presence of curved boundaries amplifies the intensity of shock waves, leading to a reduction in bubble radius, a shortened cycle, and alterations in bubble collapse dynamics.
