摘要
高层建筑多层地下室内人防结构顶板核爆荷载的合理确定是目前人防结构设计中亟待解决的问题。文中在对实际工程的调查基础上,研究了双层地下室的试验模型,进行了空气冲击波在地下室模型内传播的爆炸试验,分析了作用在双层地下室底层结构顶板的爆炸压力分布特性,并得出多层地下室的底层顶板核爆荷载一般要小于单层地下室顶板核爆荷载设计值的结论.
How to reasonably determine the nuclear dynamic loads on the cover-board of multi-storeyed basements is an urgent problem to solve in the civil defense design. The testing model of multi-storeyed basements and explosive test of shock wave propagation in the model are studied based on the investigation of practical projects, and the characteristic of explosive press distribution on the cover-board of multi-storeyed basements is analyzed. The results show that the nuclear dynamic loads on the cover-board of multi-storeyed basements is smaller than that of single-storeyed basements.
