摘　　要：由于仓壳圆筒与仓壳锥体连接部分在几何上的不连续性,造成应力集中。通过对该部位的受力分析,得出对于大直径料仓,仓壳锥体圆周方向力Q为负值的结论,并且讨论了料仓设计标准中关于许用压缩应力的计算,给出了比较合理的选取。For the geometrical discontinuity, the stresses concentration on the connection between silo cylinder ＂and hopper. Through the stress analysis on this position, the conclusion shows that for the large diameter silo, the circumferential force Q of silo hopper is negative. In addition, the caculation of allowable axial compressive stress in deferent silo design standards are discussed, and a better choice is given.
