预应力混凝土圆形筒仓的设计思想及工程实践

DESIGN THOUGHT AND ENGINEERING PRACTICE OF A PRESTRESSED CONCRETE ROUND SILO PROJECT

京阳水泥公司熟料筒仓采用预应力结构体系，在穿索、张拉、灌浆施工中均采取了具体措施，在预应力钢绞线张拉伸长值的计算中采用了更精确的方法，使结果更加符合实际。

The design of the Jingyang Cement Mill's clinker silo has been adopted with a prestressed concrete structure system.All construction has been adopted with practical measures such as constructions of cable' s penetrating,stretching and grouting etc.During the stretching procedure of steel cable,their length extension rate has been calculated with a more accurate method and thereby their results have been more consistent with practical situation and condition.
