摘要: 采用缩比试验和数值模拟相结合的方法对核电厂高配筋率钢筋混凝土结构的冲击损伤破坏模式进行研究。通过系统的钢筋混凝土靶板冲击试验获得了核岛结构在冲击荷载下典型的破坏模式（侵入破坏、侵彻震塌破坏、临界贯穿破坏、贯穿破坏）及侵入深度、临界贯穿速度的典型试验数据规律。通过数值模拟研究，建立了一套核电厂钢筋混凝土结构在刚性飞射物冲击作用下的高精度数值模拟方法，研究结果对核电厂抗飞机撞击防护及其他民用设施抗冲击防护具有重要的指导意义。Abstract: A combined method of scale-down test and numerical simulation was used to study the impact damage mode of reinforced concrete structure with high ratio in nuclear power plant under high-speed impact. The typical damage mode (penetration damage mode, scabbing damage mode, just penetration damage mode, perforation damage mode) and the typical test experimental rules of penetration depth, and just penetration velocity under impact load were obtained through systematic reinforced concrete target slab impact test. Through numerical simulation research, a series of high-precision numerical simulation methods for nuclear power plant reinforced concrete structure under the impact of projectile were obtained. The research result has important guiding significance for the anti-aircraft impact protection of nuclear power plant, and even the anti-impact protection of other civil facilities.
