高强度岩石侵彻经验公式

侵彻经验公式大多是建立在土及混凝土实验基础上的，将这些经验公式应用于岩石尤 其是高强度岩石是需要通过新的实验来验证的。在对侵彻岩石典型经验公式和花岗岩正侵彻实验 数据的对比分析基础上，确定了用于预估高强度岩石侵彻深度的经验公式，公式与实验数据一致性 较好，可用于高强度岩石侵彻深度预估。

An Empirical Equation for Penetration Depth of Projectiles into High-strength Rock Targets

Empirical penetration equations are mostly based on experiments with soil and concrete targets. These penetration equations must be experimentally validated for rock targets especially highstrength rock targets. In this paper, the typical empirical penetration equations for rock targets are introduced. A series of normal penetration experiments on granite targets were made. The depth of penetration is compared with these empirical equations. On these bases, a new empirical equation for depth of projectile penetrating into high-strength target was established. The result derived from the new empirical equation is identical with experimental result.
