装配式钢板混凝土地下粮仓结构方案研究

Structural Design Scheme Analysis of Precast Steel-Concrete Composite Underground Silos

结构设计方案是结构设计的关键问题之一。针对大直径钢筋混凝土地下粮食筒仓存在的施工工期长、成本高、防水差问题,首次提出了一种装配式钢板-混凝土地下粮食筒仓的结构设计方案,重点阐述了其节点设计方法,并与目前的钢筋混凝土地下粮食筒仓的结构设计方案进行了对比分析。分析结果表明,装配式钢板-混凝土地下粮食筒仓结构设计方案更优,有望推动今后地下粮仓的推广应用。

Structural design scheme is the key to structure design.For the existing problems of reinforced con⁃crete underground silos with large diameter,such as long construction time,high cost and poor waterproof,a structural design scheme of precast steel-concrete composite underground silos was proposed for the first time.Its design method of joints was explained in detail.The structural design scheme was compared with the current reinforced concrete underground silos.The results show that the structural design scheme of precast steel-concrete composite underground silos is much better.It’s hoped that the application of underground silos are promoted by the new scheme.
