利用ANSYS/LS-DYNA软件建立了混凝土钢丝骨架夹芯墙有限元模型，分析了单独冲击波作用、单独破片作用及二者复合作用下混凝土钢丝骨架夹芯墙位移响应的差异，探究了不同混凝土轴心抗压强度、钢丝骨架屈服强度、聚苯乙烯泡沫密度、斜插丝角度及布置方式、两侧混凝土及泡沫厚度、炸药比例距离和高度以及破片尺寸对混凝土钢丝骨架夹芯墙位移响应的影响。通过试验进行了对比验证，结果表明：建模方式是可靠的；单独冲击波作用下墙体的位移要大于单独破片作用及二者复合作用下的位移，但是在二者复合作用下墙体会产生更严重的损伤破坏；随着混凝土轴心抗压强度以及两侧混凝土厚度的提升，结构抗爆性能增强；钢丝骨架屈服强度及聚苯乙烯泡沫密度对结构抗爆性能的影响微弱；不同斜插丝角度及布置方式对结构抗爆性能影响较大；炸药高度位置对墙体损伤影响不大；当炸药比例距离一定时炸药量越大墙体损伤越严重；从墙体损伤角度分析时破片尺寸越大墙体损伤越严重。

The finite element model of concrete steel wire skeleton sandwich wall was established by ANSYS/LS-DYNA. The difference of displacement response of concrete steel wire skeleton sandwich wall under the action of shock wave, fragment, and a combination of the two was analyzed. And the influence of different axial compressive strength of concrete, steel wire skeleton yield strength, polystyrene foam density, angle of the inclined plug wire and arrangement, the thickness of the concrete on both sides and the bubble, the proportion of explosive distance and height and fragment size on the displacement response of concrete steel wire skeleton sandwich wall was investigated. The comparative test results show that the modeling method is reliable. The displacement of the wall under the action of single shock wave is greater than that under the action of single fragment and the combined action of the two, but the combined action of the two causes more serious damage to the wall. With the increase of the axial compressive strength of concrete and the thickness of concrete on both sides, the anti-explosion performance of the structure is enhanced. The steel wire skeleton yield strength and the density of polystyrene foam have little influence on the anti-explosion performance of the structure. The different angle and arrangement of diagonal filaments have great influence on the anti-explosion performance of the structure. The explosive height has little effect on the wall damage. When the proportional distance is fixed, the larger the explosive amount is, the more serious the wall damage will be. From the angle of wall damage, the larger the fragment size, the more serious the damage.
