进行了12．7mm穿甲枪弹侵彻钢管约束混凝土和PVC管约束混凝土厚靶试验，建立了硬芯枪弹侵彻深度公式，研究了钢管约束混凝土的抗侵彻性能。结果表明：钢管约束混凝土靶的破坏模式与无约束混凝土靶存在显著不同，其核心混凝土侧面出现了环向裂纹；相对于无约束混凝土靶，钢管约束混凝土靶的抗侵彻能力明显提高，并具有较强的抗多发打击能力。

Experiments of steel tube confined concrete targets impacted by 12.7mm armor piercing projectile were firstly carried out,and then the depth formula of hard core projectile was established to explore the anti-projectile performance of steel tube confined concrete targets.The results show that the failure mode of steel tube confined concrete targets differs a lot from the failure mode of the unconfined concrete.The steel tube confined concrete targets develops hoop cracks on side face and works better in anti-projectile performance than the infinite concrete targets.Steel tube confined concrete targets also work well against multi-impact.
