摘要: 为了估算混凝土板在外来飞射体撞击下的侵彻极限深度与痂斑极限厚度，总结了以往试验与理论研究成果，评价了几种有代表性的经验公式，对4种具有不同特征参数的导弹撞击混凝土板时的侵彻极限深度与痂斑极限厚度进行了对比。结果表明，现有的经验公式估算侵彻极限深度的差异不大，而估算痂斑极限厚度有时差异较大。

Abstract: This paper summarizes some test and theoretical results and evaluates several experimental formulas for estimating the penetration and scabbing limit thickness of concrete targets under projectile impact. The parameters of four types of missiles with different characteristics and concrete targets are given. The corresponding penetration and scabbing limit thicknesses are calculated under different velocities. The results indicate that there are minor difference in estimating penetration but significant difference in estimating scabbing limit thicknesses using existing experiential formulas.
