| 中文摘要: |
| 本文从理论依据、侧压比、计算基本参数及进卸料偏心等因素采用的放大系数等方面对中美欧筒仓规范中浅仓的贮料压力计算公式进行了研究。并结合某工程25m直径的钢筋混凝土熟料库，在不同的高径比的情况下，对三本规范计算所得的仓底压力、仓壁水平压力及仓壁摩擦力的变化趋势做了对比。探讨了季节温差与内外温差对仓壁内力的影响，结果表明内外温差会对仓壁产生较大的环向与竖向弯矩，在实际分析设计中应予以充分重视。 |
| 英文摘要: |
| The formulas of stored material pressure for shallow silo were studied from the theoretical basis, lateral pressure ratio, basic parameters and amplification factors in the filling and discharge process under the code of Chinese, European and American. In combination with a clinker silo with diameter 25 m, the vertical, lateral and frictional pressure difference were compared in different codes with series slenderness ratio. The influence of the seasonal temperature and internal and external temperature difference on the silo is discussed, results shows that the latter would have bigger effects to the hoop and vertical bending moment, it should be paid more attention in the design. |
