摘要:
本文首次将预应力槽型板应用于人防结构中,为研究装配式预应力槽型板结构体系在设计人防荷载作用下的抗爆性能,本文对缩尺比为1∶3的槽型板进行了模拟核爆试验,分析大跨预应力槽型板结构在人防爆炸荷载作用下的动力性能、变形性能.再对有限元模型在4级爆炸等级作用下进行模拟分析,并与试验结果对比.研究结果表明:在核5级人防荷载作用下试验构件完好,仅在构件底部受拉区和端部剪切区出现少量裂缝;在核4级作用下,结构未发生脆性断裂,说明合理设计的装配式预应力混凝土槽型板可以用于4级的人防工程;也证明了装配式预应力混凝土槽型板具有良好的位移延性,不会发生脆性破坏,可用于抗爆结构;通过模拟分析,验证有限元模拟的真实性以及分析结果的可靠性
Abstract:
In this paper, prestressed channel slab is applied to civil defense structure for the first time In order to study the blast resisting performance of prefabricated prestressed groove slab structure system under the load of civil defense, this paper carried out the nuclear explosion simulation experiment on channel slab with the scale ratio of 1∶3, and analyzed the dynamic performance and deformation performance of the large-span prestressed groove slab structure under the action of the load of civil defense. Then the finite element model was simulated and analyzed under the action of grade 4 explosion and compared with the test results. The results show that the test components are intact under the action of nuclear grade 5 civil defense load, and only a few cracks appear in the tensile zone at the bottom of the components and the shear zone at the end. Under the action of nuclear level 4, there is no brittle fracture of the structure, which indicates that the prestressed concrete groove plate with reasonable design can be used in civil defense engineering of grade 4. It is also proved that the prestressed concrete groove slab has good displacement ductility and does not have brittle failure. Through simulation analysis, the authenticity of finite element simulation and the reliability of analysis results are verified.
