As to evaluate effectiveness of earth-penetrating projectile, the effectiveness evaluation theory of earth-penetrating projectile is established. The theory includes the structure earth-penetrating projectile analysis, underground target analysis, penetration analysis, damage analysis, damage evaluation of personnel target and non-personnel target.Firstly, analyzing parametric includes the mass, diameter and caliber-radius-head of earth-penetrating projectile, the structure of underground target and agent of protection. Secondly, the model of penetration about earth-penetrating projectile is established, based on spherical cavity-expansion theory in composite agent of soil and concrete, and penetrating depth of some influence factors are analyzed. Damage influence factors and damage effect is analyzed when projectile is detonating. Finally, the model of effectiveness evaluation about earth-penetrating projectile is established, based on penetrating depth and damage effect. Compare three types of earth-penetrating projectiles and evaluate the effectiveness of earth-penetrating projectiles. Meanwhile the deeper of earth-penetrating projectile and the more charge weight are, the better the effectiveness is.
