Optimal design method of anti-explosion plate with shell-like structure
The invention discloses an optimal design method of an anti-explosion plate with a shell-like structure. The anti-explosion plate comprises a plurality of ultra high toughness cementitious composite (UHTCC) energy absorption layers and ultra high performance concrete (UHPC) anti-explosion layers which are alternately arranged, and both an explosion facing surface and an explosion backing surface located on the outer layer of the anti-explosion plate are the UHTCC energy absorption layers. The thickness of the anti-explosion plate is determined according to the explosion impact load resistancegrade and the anti-explosion fortification requirement, the thickness of the UHTCC energy absorption layers is determined through the energy absorption effect, and the thickness of the UHPC anti-explosion layers is determined according to the load grade and the explosion pit-opening requirement. By means of the optimal design method, the pit-opening depth under the explosion load can be effectively reduced, the phenomena of seismic collapse and fragment splashing of the explosion backing surface of the anti-explosion plate are reduced, the explosive shock wave absorption capacity of the anti-explosion plate is enhanced, and the safety of personnel and equipment behind the structure is protected.
本发明公开一种仿贝壳结构的抗爆板优化设计方法，所述抗爆板包括若干交替排布的超高韧性水泥基复合材料UHTCC能量吸收层和超高性能混凝土UHPC抗爆层，位于所述抗爆板外层的迎爆面和背爆面均为UHTCC能量吸收层；根据抗爆炸冲击荷载等级以及抗爆设防要求，确定抗爆板的厚度，其中UHTCC能量吸收层的厚度通过能量吸收效果确定，UHPC抗爆层的厚度由荷载等级和爆炸开坑要求确定。该优化设计方法能够有效减少爆炸荷载下的开坑深度，减少抗爆板背爆面的震塌、碎片飞溅现象，增强抗爆板对于爆炸冲击波的吸收能力，保护结构后方人员和设备的安全。
