摘　　要：针对双向空腹密肋梁楼盖是一种受力性能优越、造价经济、更符合大跨度、大空间结构体系的要求,对现浇混凝土双向空腹密肋梁楼盖在地下室顶板中的受力特点、设计方法、结构体系形式进行了研究.利用PK-PM软件对工程实例进行计算.结合在实际工程中的应用,分析了钢筋混凝土密肋楼盖的施工工艺.介绍了钢筋混凝土双向空腹密肋楼盖结构体系对于大空间地下室建筑的应用.Bidirectional hollow ribbed floor possesses excellent stress performance. It is economical, more applicable to large-span,large-space structural system. The paper researches cast-in-place concrete twoway hollow ribbed beam floor in the basement stress characteristics, design method,and structure form. The PKPM software is employed in the project example. Combined with the application in the practical engineering ,analysis of the reinforced concrete rib floor construction technology was conducted. The application of the reinforced concrete two-way hollow ribbed floor structure system for large space basement construction was introduced.
