摘要	在混凝土中掺入玄武岩纤维虽可提升抗爆性能，但其在水下爆炸下的毁伤程度仍较显著，需进一步优化防护措施。迎爆面设置牺牲防护层是一种高效方法，而高聚物材料因其成型迅速、密度低、吸能效果佳，在抗爆领域具有潜在优势。制作了玄武岩纤维混凝土板试件，开展空中与水下接触爆炸试验，获取毁伤形态；建立了玄武岩纤维混凝土板接触爆炸数值模型并验证了其有效性。随后在模型中设置高聚物牺牲层，分析了不同厚度和不同装药质量下混凝土的毁伤形态、吸能特性及损伤体积分数，结果发现高聚物牺牲层可吸收66%-84%的爆轰能量，显著降低冲击波能量及应力集中，毁伤模式由贯穿裂缝转为局部剥落，有效减轻爆炸荷载对混凝土板的毁伤。
Abstract	Although incorporating basalt fibers into concrete can improve its blast resistance, the damage level remains significant under underwater explosions, necessitating further optimization of protective measures. Placing a sacrificial protective layer on the blast-facing surface is an effective approach, and polymeric materials exhibit potential advantages in blast mitigation due to their rapid formability, low density, and excellent energy absorption properties. In this thesis, basalt fiber-reinforced concrete slab specimens were prepared, and contact explosion tests under both air and underwater conditions were conducted to assess damage patterns. A numerical model for the basalt fiber-reinforced concrete slab under contact explosion was established and validated. Subsequently, a polymeric sacrificial cladding was introduced into the model, and the damage morphology, energy absorption characteristics, and damage volume fraction of the concrete were analyzed under varying layer thicknesses and charge masses.The results demonstrate that the polymeric sacrificial cladding can absorb 66%–84% of the detonation energy, significantly reducing shockwave energy and stress concentration. The failure mode shifts from penetrating cracks to localized spalling, effectively mitigating blast-induced damage to the concrete slab. These findings provide valuable insights for the design of blast-resistant composite structures.
