摘　　要：本文就一工程实例对人防地下室常用肋梁楼盖体系进行了分析,就柱网的合理布局和边跨的合理设计问题进行了探讨,并对整浇梁板共同工作问题进行了初步的考虑。结果表明,在相同设计条件下,合理的楼盖体系的选择应根据抗力级别确定;柱网宜设计成矩形,正交跨长比取0.65~0.7最合适;边跨取0.8~0.85倍内跨更合理;设计时应考虑整体现浇梁板共同作用的特性和原理,将现浇板作为框架梁的翼缘,共同参与受力分析。Based on an actual project,the conventional girt strip roof system of civil air defence basement was analyzed.Then the proper redistribution of column mesh and rational design of side span was discussed yet in the paper,and the cooperation effect of integral pouring beam-slab was considered initially.The results show that,rational design of roof system is up to resisting class in the same design conditions;rectangle is fit for column mesh,the best radio of orthogonal span is 0.65~0.7;the best length of side span is 0.8~0.85 times the length of interior span;the cooperation character of integral pouring beam-slab shoule be considered when designing,and the slab should be put as the flange of frame beam,engaging in stress analysis together.
