摘　　要：对聚氨酯泡沫铝夹层混凝土结构进行落锤冲击试验,通过对不同聚氨酯泡沫铝吸能层厚度、不同冲击高度和不同结构组合型式的研究,得出结论:聚氨酯泡沫铝吸能层越厚,复合结构吸收的能量越多,但是增益效果随着吸能层厚度的增大而降低;对能量吸收有一个适用的冲击高度范围,在范围内可以有效发挥聚氨酯泡沫铝变形吸能能力;双夹层结构的抗冲击效能要好于同厚度单夹层结构。Through the polyurethane foam aluminum sandwich drop weight impact test of concrete structure,based on the researches of different polyurethane foam aluminum absorption layer thickness,different impact height and different structure combination,the conclusion is showed:more thicker was the polyurethane foam aluminum absorption layer,more energy absorption by the complex structures,but energy absorption effect change trend with the increase of energy absorption layer thickness decreases;Impact on the height of the energy absorption had a scope,within the scope polyurethane foam aluminum can be effectively play deformation energy absorption capacity;Double sandwich structure impact performance better than the single sandwich structure with thickness.
