后张法预应力筋理论伸长值的计算及应用

Calculation and analysis of elongation in theory with post-tensioning inherent stress of tendons

在高速公路施工中,依据公路桥涵施工技术规范与设计图纸,从钢绞线实际受力情况分析了其理论伸长值的计算。通过应用得出,理论伸长值在实际张拉时与实际伸长值是十分吻合的,均无超过±6%的范围。

In the highway construction, according to the bridge and culvert construction technology criterion and design drawing, the steel wires elongation in theory in the case of the actual stress. After the application.
