摘　　要：在化爆土中自由场波传播理论的基础上,采用介质结构相互作用理论和双剪强度理论对无梁板结构冲切破坏机构进行了分析,建立了无梁板结构的冲切抗力模型和动力响应方程,分析结果与试验结果符合较好。Based on the wave propagation theory of the free field in soil under the conventional weapon burst circumstances, the analysis of the punching failure mechanism of slab-column connection is performed using the structure medium interaction theory and the twin shear strength theory. The resistance model of structure and the equation of motion for the structure are established. The calculated results are in good agreement with the experimental ones.
