摘　　要：基于叠加原理,利用炸药接触面起爆方式,实现对可压缩固体材料的矩形波加载.通过联立爆炸产物和可压缩固体的(u,p)曲线以及综合考虑炸药与材料试件各自由边所受稀疏波干扰情况,从理论上给出冲击波平台压力和冲击波加载平台宽度的计算方法,为将来利用接触爆炸实现对材料试件的近似矩形波加载提供理论基础.Based on the principle of superposition, an explosive contact surface detonation model is used to achieve the rectangular wave loading on a compressible solid material. Via integrating the （u, p） curve for the explosion products and the compressible fluid, the shock pressure and the shock wave loading platform width are obtained with con-sideration of the interference from the sparse wave in explosives and materials at their free edges. Theoretical analysis provides a theoretical foundation for the substantially rectangular wave loading of specimens using the contact explo-sion in the future.
