夹层玻璃的抗爆设计有利于抵抗爆炸冲击波对人员的伤害． 传统的抗爆设计 p-i图法(p 为超压，i 为单位面积正冲量)未考虑爆炸负压段的影响，而负压段会显著影响夹层玻璃的动态响应． 为此，文中采用有限元法就爆炸负压段对 p-i 图抗爆设计方法的影响进行了仿真，针对 p-i 图抗爆设计方法的不足，提出了抗爆设计的 W-R法(W 为炸药当量，R为爆炸距离)． 相比于 p-i 图，W-R图更具规律性和直观性，W-R公式形式更为简单，用于抗爆设计更具可行性． 文中还定性分析了玻璃几何参数对夹层玻璃抗冲击性能的影响，以玻璃临界破坏为基准，得到了评估夹层玻璃抗爆性能的 W-R经验公式，可为夹层玻璃抗爆设计提供指导．

 he blast resistance design of laminated glass helps to reduce the personal injury caused by explosive
blast． The traditional blast resistance design with p-i diagram，where p is overpressure and i is positive impulse per unit area，does not take into consideration the effect of negative phase of blast． However，the negative phase can significantly affect the dynamic response of laminated glass． In order to solve this problem，the effect of the negative phase of blast on the p-i diagram is simulated by means of the finite element method． Aiming at the deficiency of the p-i diagram design method for blast resistance，a design method named W-R method，where W refers to explosive equivalent and R refers to explosion distance，is developed for blast resistance． In comparison with the p-i diagram design method，the W-R design method is more feasible for the blast resistance design because the W-R diagram has a simpler form and is more regular and more intuitional． Furthermore，the effects of the geometric parameters of laminated glass on its impact resistance are qualitatively analyzed，and by taking the critical damage of laminated glass as the benchmark，an empirical W-R formula is fitted to evaluate the blast resistance of laminated glass，which can provide guidance for the blast resistance design of laminated glass．
