Because the height of box girder is limited, vertical prestressed bar is short, so when control stress of prestressing is attained, elongation of thick high strength thread reinforcing bar is limited.

这是由于箱梁的高度有限，竖向预应力筋的长度都比较短，因而在达到张拉控制应力时高强精轧螺纹粗钢筋的伸长量有限。

This research job analysised the extending roll pass system the finish roll pass system and the ultimate roll groove. The mathematical models and experience formulations used for roll pass design are corrected according to the basic theory and the practical experience of the engineerings. The thread steel bar CARD was set up with the visual program tool-VisualBasic6.0, based on the method of the structural program design.
