摘要

摘要: 高聚物材料具有成型快和膨胀性能好的特点，该材料与碎石和钢筋的复合结构应用于地基处理和城市道路脱空除险加固，具有明显优势。本文中，设计并制作了高聚物碎石板和钢筋高聚物板，开展了接触爆炸冲击下的试验研究，通过毁伤尺寸和所测冲击波数据探讨了2种板的毁伤特性。基于ANSYS/AUTODYN非线性显式有限元程序，建立了试验中毁伤更严重的钢筋高聚物板的接触爆炸全耦合模型，并通过与试验结果的对比，验证了所建耦合模型的准确性和适用性。参数化分析了钢筋高聚物板对炸药量和板厚的敏感性，并利用多参数非线性回归分析方法，提出了钢筋高聚物板迎爆面和背爆面破坏直径的预测公式。结果表明：接触爆炸作用下，高聚物碎石板的毁伤模式以接触部位的局部震塌冲切破坏为主，除此之还有一些毁伤裂纹；钢筋高聚物板的破坏模式主要是迎爆面爆坑毁伤、背爆面剥落损伤和中心冲切贯穿破坏。高聚物碎石板和钢筋高聚物板对爆炸冲击波都具有良好的衰减作用，有望应用到抗爆炸冲击防护领域。

Abstract: Polymer materials have the characteristics of fast forming and good expansion performance. Their composite structures with gravel and reinforcement have obvious advantages in foundation treatment and urban road void removal and reinforcement. As reported in this paper, polymer gravel slabs and reinforced polymer slabs were designed and manufactured, and experimental study under contact explosion impact was carried out. The damage characteristics of the two kinds of slabs were investigated through the damage sizes and the measured shock wave data. Based on the ANSYS/AUTODYN nonlinear explicit finite element program, the damage modes and damage diameters of the reinforced polymer slabs were explored, and compared with the experimental results to verify the accuracy and applicability of the established finite element model. The sensitivity of the reinforced polymer slabs to explosive quantity and slab thickness was analyzed parametrically, and the prediction formula of the failure diameter of the top surface and bottom surface of the reinforced polymer slab was proposed by using a multi-parameter regression procedure. The results show that under the action of air contact explosion, the damage mode of the polymer gravel slab is mainly local collapse and perforation at the contact part. Under the impact load of contact explosion, punching and cutting explosion pits appear on the top surface of the slab, tensile failure and collapse area occur on the bottom surface, and a through failure hole is formed in the center of the slab, in addition to some damage cracks. Under the action of air contact explosion, the reinforced polymer slab mainly exhibits crater damage on the top surface, spalling damage on the bottom surface and central punching perforation damage. The reinforced polymer slab has a good attenuation effect on the explosion shock wave. The diffuse reflection effect of the closed bubble in the polymer structure on the shock wave can absorb more energy to alleviate the explosion shock wave, indicating that the polymer has the potential to be applied to the anti-explosion shock protection.
