外包钢板地下散装粮仓仓壁构造及受力分析

Construction and force analysis of the wall of underground bulk grain silo enclosed with steel

为加强地下钢筋混凝土圆形散装粮仓的防水效果,把外包钢板技术引入到地下仓的建造中,把防水与结构受力有机结合起来。在空仓与满仓工况下,利用ABAQUS有限元对筒仓进行分析,可知采用外包钢板地下粮仓形变分别为钢筋混凝土地下粮仓的25.8%与14.25%,通过对仓壁进行经济分析,与钢筋混凝土地下粮仓相比,外包钢板地下粮仓可节约混凝土用量28.19%,节约钢材用量75.20%,因此外包钢板地下粮仓具有良好的结构稳定性与经济性。

In order to strengthen the waterproof effect of concrete circular underground bulk grain silo, the steel - enclosed concrete technology is introduced into the construction of the underground warehouse to combine the waterproof measures and structure force analysis. The silo was analyzed by ABAQUS finite element in the conditions of empty and full. The results showed that the deformations of the silo enclosed with steel were 25. 8% and 14. 25% of the reinforced concrete underground silo, respectively. 28. 19% of concrete and 75.20% of steel were saved by using enclosing with steel, compared with reinforced con-crete underground silos, through the economic analysis. So the underground concrete silo enclosed with steel had good structural stability and economic benefits.
