摘　　要：混凝土圆形筒仓的主体为壳体结构,是水泥生产企业中常见的用于储存散料的大型构筑物,通常采用滑模工艺建造。近年来,陆续发现部分筒仓的仓壁存在网状裂缝,影响了结构的正常使用及耐久性能,其中少数仓壁严重开裂后降低了筒仓整体结构的安全度。针对该问题进行了研究,提出了改进混凝土筒仓结构设计与施工的技术建议、及加固已开裂混凝土仓壁的方法。Main part of concrete silos is the cylinder shell structure,which is generally used as the large store building in cement factories,and is usually built in way of slipforming construction.In recent years,as gridded cracks appear on the wall of some concrete silos,the serviceability and durability of these silos are impaired;furthermore the design security of a few silos is reduced as their wall has cracked seriously.Based on studies on the problem in concrete silos,some technical advices to improve the structural design and construction,as well as the strengthening method for the cracked silo wall,are proposed in this paper with detailed analyses.
