摘　　要：弹体侵彻混凝土是一个复杂的过程,可通过缩比试验来进行研究。文中运用量纲分析和相似理论对弹体侵彻混凝土靶板进行了相似率研究,得到不同尺寸弹体对混凝土进行侵彻的数据,结果表明侵彻深度与弹体速度之间存在近似的线性关系,同时对影响相似性的原因进行了分析。Projectile penetration into concrete is a very complicated question. It is applicable to use scale model in the experiment in such research. The similitude rules of projectile penetrating into concrete thick sheet have been studied using dimension analysis method and similitude theory. The similarity of different scale projectile penetration into concrete is studied under simulative test. The result show that there is an approximate linear relation between depth and speed as projectile at high speed penetrates into concrete. Reasons are suggested of similarity is not strictly adherence to the procedures of projectile penetrations into concrete.
