摘要
通过对各种形式先简支后连续T梁桥的研究,提出一种后穿连续长束的方案,研究表明:在同等跨度和承载能力的情况下,该方案具有减少锚头数量、降低负弯矩区预应力总量30%以及减少收缩徐变对结构的影响且收缩徐变的影响仅为后连续短束的40%左右等优点。
Through the analysis of simply supported and continuous T beam,it puts forward a new scheme of the post continuous long bundle.The research shows that in the case of same span and loading capacity,this scheme can decrease the quantity of anchors,reduce the sum of pre-stress of negative bending moment by 30 percent,and lessen the influence of shrinkage and creep to structure at almost 0.4 time of the post continuous short bundle.
