摘　　要：结合夏汾高速公路中桥预应力钢筋混凝土的施工 ,对预应力空心板的钢绞线张拉和灌浆进行了分析 ,从施工中的材料及机具的选用、施工工艺流程、施工要点等方面进行了论述 ,提出了切实有效的施工方法 ,对施工工程中常见通病的预防作了研究 ,通过采取相应的技术措施 ,应力延伸双控制 。Combined with the prestressed concrete construction in Xiafen express highwayteh the steel strand's tension and grouting of prestressed hollow plate are analyzed. From the choosing of materials and equipments, construction technological process, construction key points the construction is wholly discussed. Effective construction method is proposed and the faults commonly exited in construction process are studied. At last the corresponding technical measures stress extension double control is adopted and make good benefit.
