摘　　要：岩石类靶体侵彻研究紧贴防护需求,深入分析弹体高速侵彻下靶体毁伤机制,对确定防护层最小安全厚度、提升地下工程防护能力有重要意义。为全面了解宽速域、多形式的侵彻效应,系统总结岩石类靶体的侵彻试验和不同侵彻状态下的理论分析模型,分析弹体侵彻过程及靶体毁伤机制。此外,将预测弹体侵彻深度的解析和经验计算公式进行分类,对比分析弹体侵深影响因素,梳理超高速侵彻下岩石类靶体毁伤破坏效应,对未来超高速武器打击下地下工程防护能力的提升提出建议。The study of rock-type target penetration can satisfy the protection requirement of underground engineering.An in-depth analysis of the damage mechanism of the projectile penetrating the target at high speed is of great significance for determining the minimum safety thickness of the protective layer and improving the protective ability of underground engineering.In order to fully understand the effect of wide velocity domain and various forms of penetration,this paper systematically summarized the penetration tests of rock-type targets and the theoretical analysis models under different penetration conditions,and analyzed the penetration process of projectiles and the damage mechanism of targets.In addition,it classified the analytical and empirical calculation formulas for predicting the penetration depth of projectiles,compared and analyzed the corresponding influence factors,sorted out the damage effects of rock targets under ultra-high-speed penetration,and put forward recommendations for improving the protection of underground engineering under potential ultra-high-speed weapons attack in the future.
