摘　　要：分析和总结了水下爆炸现象数值模拟以及水下爆炸作用下结构响应的数值计算研究进展。首先概述了水下爆炸现象包括装药的爆轰、冲击波的产生和传播、气泡的形成和脉动三个阶段数值计算的研究情况;接着阐述了地震波作用下、水中冲击波作用下、气泡脉动压力作用和多种载荷同时作用时结构响应的数值研究概况;最后对此课题的研究方向提出了几点建议。The researching development of numerical simulation of structural responses to underwater explosion is reviewed in the paper in terms of the numerical value calculations in the three stages detonation,the generation of air bubbles and their impulsion,and the generation of shockwaves and their transmission. The numerical simulations of structural responses to underwater explosion, which is resulted form earthquake wave, shoekwaves, bubble impulse, combined forces, are also summarized respectively. Some suggestions are made for the researching direction in this field.
