摘　　要：介绍了水下爆炸试验中的相似理论,在分析结构相似律的基础上,详细讨论了相似理论在水下爆炸模型试验中的应用方法,探讨了该方法的应用前景及局限性。现阶段,由于涉及到巨额经费开支、环境保护等问题,特别是试验难度大、周期长,在我国对每型首制舰进行实船爆炸试验考核是不现实的,因此利用相似理论预测舰船结构对水下冲击的响应,是较为有效的手段。本文利用量纲分析的方法,简要分析了水下爆炸中的相似律,并应用已有的试验结果加以验证,对于今后的模型试验有一定的借鉴作用。This paper briefly introduces the scaling laws in the underwater explosion tests. Based on structural similitude, this paper mainly discusses the applicability of scaling laws to underwater explosions. The applicability and limitations of classical scaling relationships are reviewed in the paper. In recent tines, because of an hugeness cost and environmental constraints, it is unpractical to make underwater shock trials for the lead ship of each new conduction in China. It is valid means to predict structural response to a shock wave produced by a far-field underwater explosion. This paper validates the applicability and limitations of classical scaling relationships with old test results. This will be valuable to underwater explosion tests and studies aftertime.
