摘　　要：矮塔斜拉桥亦称部分斜拉桥,就其受力特性而言,矮塔斜拉桥是介于梁式桥与斜拉桥之间的新型桥型。如果说梁式桥属于刚性桥型,斜拉桥属于柔性桥型,那么矮塔斜拉桥则具有刚柔相济的结构特性。由于矮塔斜拉桥优越的结构性能和良好的经济指标,越来越显示出巨大的发展潜力。为了进一步研究矮塔斜拉桥的力学特性,本文经对秋浦河宽幅矮塔斜拉桥进行长期施工监测的基础上,经分析得出相关结论,可为同类桥型提供参考。The extradosed cable-stayed bridge is a new bridge structure form between beam bridge and cable-stayed bridge on its characteristic under force,which is also called as partial cable—stayed bridge.If it is said that the beam bridge belongs to rigid bridge type and the cable—stayed bridge is flexible one,while the extradosed cable-stayed bridge presents structural characteristic both of them.As a result of superior structural property and well economic index of itself,the extradosed cable-stayed bridge displays more and more enormous development potentiality.In order to study the characteristic under force of the extradosed cable-stayed bridge further.This paper based on consrtuction monitoring of the extradosed cable-stayed bridge on Qiupu river after a long time,and received some conclusion after analysis of date.Similar to the future construction of the bridge Can be provided from it.
