本文基于点源爆炸理论，建立了面源、线源和点源TNT装药强爆炸解，填补了面源与线源强爆炸解的空白；采用真实空气状态方程进行分析计算，研究了真实空气条件下球形TNT装药爆炸近区冲击波的传播特性。通过算例分析，计算结果与已有文献资料数据吻合较好。本文的研究成果对爆炸力学和防护工程研究起到了重要的参考作用。

Based on the explosion theory of point source, this study obtains the solution of a strong explosion of one-dimensional TNT point source charge, line source charge, and plate source charge blasting in a close-in flow field. Furthermore, this study investigates the propagation characteristic in the close-in field of a shock wave of the TNT spherical charge explosion in real air condition by using the dimensional state equations of real air and the detonation products of a TNT spherical charge. Based on the analysis of the examples, the study results are largely consistent with that of some existing literature. These research results provide an important reference for studying explosion mechanics and protection engineering.
