摘要

Contemporary research on near-surface explosions predominantly examines shock waves and bubbles, while investigations into explosion-generated waves remain limited. In naval combat scenarios, explosion-generated waves present a substantial threat to vessels, potentially resulting in catastrophic outcomes. This paper examines the characteristics of waves generated by near-surface explosions, specifically focusing on wave propagation patterns under varying explosive configurations and marine conditions. The Structured Arbitrary Lagrangian-Eulerian (S-ALE) method is employed to simulate and analyze wave characteristics resulting from near-surface explosions, seeking to understand surface movement behavior under diverse conditions. The research demonstrates that dual explosion charges produce more intense waves compared to single explosion charges of equivalent explosive force. Within the wave field, explosion-generated waves can enhance the roll and pitch movements of structures by 50% to 150%.
