本文主要研究内容
作者林智敏,刘振宇,陈小平（2019）在《南宁英华大桥主桥设计》一文中研究指出：南宁英华大桥为45 m+410 m+45 m单主缆钢箱梁悬索桥。该桥设置单主缆,主缆采用预制平行高强钢丝索股结构。全桥共布置40对吊索,均采用预制平行钢丝束。主索鞍采用全铸造结构,塔顶设有格栅底座。该桥采用散索套散开主缆,通过结构优化,有效解决了采用传统散索套所带来的索股不稳定及难以架设的技术难题。主缆锚固采用钢拉杆锚固系统,锚固方式为无粘接后锚承压式。主塔为曲面桥塔,采用文物"羊角钮编钟"作为造型元素,下塔柱为预应力混凝土结构,上塔柱为钢结构。主梁采用扁平流线型钢箱梁,全宽37.7 m,中心高3.5 m。锚碇均为重力式锚碇,由于本桥为单主缆结构,因此两岸均只在引桥正下方设1个锚碇。
