Abstract In order to study the penetration effects of high-velocity projectiles on rocks，the model experiments of high-velocity projectile penetrating rock targets are carried out by using high-velocity ballistic gun，which the highest experimental velocity reaches 1 450 m/s. The relationship between penetration depth and velocity is obtained. The empirical equation of penetration depth is established when the bullet speed is lower than the terminal speed；and the equation has a good compatibility with experimental results. The damage types of model experimental targets are analyzed；the results show that various damage types of targets are generated under different projectile velocities for a given bullet and target. The penetration performance，terminal velocity and mass loss of projectile under high impact velocity are investigated；and the elements which affect the terminal velocity and mass loss of projectile are analyzed. It can be used to predict the main parameters such as penetration depth，acceleration，mass loss rate and so on；and it also provides an effective reference to the design of projectile head and protective engineering. The results show that unweathered hard rock can be used as materials in protective engineering after comparing the experiments of concrete plate targets.

Key words： rock mechanics high-velocity penetration rock target scale-model experiment mass loss
