摘　　要：阐述了用于提高建筑结构抗爆炸冲击的常规措施,分析了在防护上存在的缺陷。砌体结构因强度较低,在爆炸事故中的破坏较为严重。聚脲弹性体可以提高墙体结构的抗爆能力,降低破坏碎片的产生。通过爆炸试验,研究聚脲弹性体加固厚度对喷涂聚脲弹性体加固砖墙和混凝土砌块墙抗爆性能的影响,聚脲弹性体能有效包裹砌体墙背爆面在爆炸荷载下产生的爆炸碎片,降低墙体的变形和位移量。This paper expounded the conventional measures to improve the anti-knock and impact of building structures and analyzed the defects in the protection.Masonry structure was damaged seriously in explosion accident because of its low strength.Polyurea elastomer can improve the anti-knock of the wall structure and reduce the generation of explosive debris.This paper focuses on the influence of the change of the thickness of polyurea elastomer reinforcement on the anti-explosion performance of brick wall and concrete block wall strengthened by spraying polyurea elastomer through the explosion test study.Polyurea elastomer can effectively wrap the explosive debris generated by the detonation surface of the back of masonry wall under the explosion load and reduce the deformation and displacement of the wall.
