摘　　要：本文以平战两用人防工程口部典型封堵方案缩尺模型试验为背景,运用结构动力学等效体系的基本方法,导出一般爆炸荷载作用下典型封堵结构立柱弹性响应的解析计算公式,计算结果与实验数据符合较好。In this paper,calculation equations are derived for the elastic response of a typical blocking-up plate-column structure used at the entrance of underground civil defence constructions under a general blast loading. Such constructions are utilized both in peace and war time. On the basis of the model experiment of the blocking-up structure, the mathematical derivation uses the general method of equivalent systems of the structural dynamics. Numerical results of the calculation are in accord with the experimental data.
