摘　　要：根据圆柱壳的有矩理论,分别对筒仓在贮料水平压力和温度作用下的仓壁内力进行分析,并与有限元的计算结果进行了对比。结果表明:对于大直径筒仓,采用有矩理论或有限元分析的仓壁内力比传统的无矩理论计算结果更符合工程实际。The inner force of silo wall subjected to stored material pressure and temperature action is analyzed based on the moment theory of cylindrical shells, and the results are compared with the finite element method in the paper. The results reveal that inner force analysis of silo wall using the moment theory and the finite element analysis are more close to practice than traditional no moment theory for large diameter silo.
