钢筋混凝土板是各种水工结构中的重要部件。因此，进行水下爆炸载荷作用下钢筋混凝土板结构的毁伤模式研究具有重要的战略意义。本文采用Abaqus声固耦合法对钢筋混凝土板在水下爆炸载荷作用下的毁伤模式进行研究，分析影响钢筋混凝土板毁伤的主要参数，总结钢筋混凝土板的几种典型毁伤模式，确定钢筋混凝土板的毁伤等级，包括轻微毁伤、中等毁伤和严重毁伤；建立Kriging模型，对钢筋混凝土板的毁伤模式进行预测，并通过算例验证预测方法的准确性。研究工作可为水下爆炸载荷作用下钢筋混凝土结构毁伤的深入研究提供参考。
Reinforced concrete slabs are important components in various hydraulic structures. Therefore, studying the damage modes of reinforced concrete slab structures under underwater explosion loads is of great strategic significance. The ABAQUS acoustic-solid coupling method was used to study the damage modes of reinforced concrete slabs under underwater explosion loads. The main parameters affecting the damage of reinforced concrete slabs were analyzed, and several typical damage modes of reinforced concrete slabs were summarized. The damage grades of reinforced concrete slabs were determined, including minor, moderate, and severe damage. The Kriging model was established to predict the damage mode of reinforced concrete slabs, and the accuracy of the prediction method was verified through examples. The research can provide a reference for in-depth research on the damage of reinforced concrete structures under underwater explosion loads.
