Experimental and numerical simulation research on damage effect of jetting projectile charge (JPC) on reinforced concrete wall

  • 摘要: 为了满足高侵深和大穿孔的要求,设计一种聚能杆式弹丸(jetting projectile charge, JPC),开展大尺寸钢筋混凝土墙的毁伤效应试验。在此基础上,基于修正参数的K&C(Karagozian & Case)模型进行数值模拟,研究JPC高速侵彻和爆炸冲击波对钢筋混凝土墙的联合破坏作用,分析墙体厚度对破坏效果的影响规律。结果表明,在1.67倍和2.50倍装药直径的炸高条件下,JPC均能够有效贯穿80 cm(6.67倍装药直径)厚的钢筋混凝土墙,形成直径大于6 cm(0.50倍装药直径)的柱状孔洞;聚能装药的多载荷毁伤特性决定了钢筋混凝土墙的破坏结果,爆炸冲击波能够加剧墙体正面开坑和背面崩落的破坏范围;墙体厚度对于墙体正面漏斗坑的直径与深度及内部侵彻孔洞直径均无显著影响;随着墙体厚度增大,背面漏斗坑直径逐渐减小,深度却逐渐增大。
