摘要
结合济南二环东路高架桥四合同十四联现浇连续箱梁预应力施工经验,探讨了施工中伸长量计算与设计图纸中伸长量的区别,介绍了如何精确计算伸长量,阐述了张拉次数的控制方法,并分析了两端张拉与一端张拉的区别,以期指导实践。
Combining with second ring road,Ji＇nan viaduct and 14 prestressed continuous box joint construction experience of place,this thesis discusses the elongation calculation difference between construction and design,describes how to accurately calculate elongation,illustrates the control method of stretching frequency,and analyzes the difference between both ends of the tension and one end of tension,in order to guide practice.
