摘要
公路工程中的匝道桥,很多是处于平面曲线上的后张法预应力钢筋砼现浇箱梁。文章对预应力筋伸长值计算是否要考虑平面曲线的影响,进行了简单地探讨。
Highway engineering ramp bridge, many of the curve in the plane of the post-tensioned cast in place reinforced concrete box girder.Articles for the prestressing tendon elongation value calculation is to consider the impact of plane curves, carried out simply to explore.
