摘　　要：采用一维波理论，考虑土－结构相互作用及中面力的影响，分析了在核爆作用下土中箱形结构顶板的动载荷，获得了一些有意义的结果．对顶板跨中压力迅速衰减给出了合理的解释．In this paper,the dynamic loading on the roof of a shallow-buried box-type structure in soil under nuclear explosion in consideration of soil-structure interaction and the effects of the compressive force in the middle surface of the roof is analysed. Some of the significant results have been obtained,especially a rational explanation for quick declination of the loading in the middle of the roof is given.
