柔性墩中央索面宽幅斜拉桥结构形式较为特殊，在主梁悬臂施工中对整体稳定、宽梁横向抗扭、索力调整及不平衡荷载控制均有十分严格的要求。结合浙江富阳鹿山大桥主桥上部结构，对独柱式塔、单箱五室箱梁、多主桁长大挂篮、环氧钢绞线斜拉索挂设、体系转换等关键施工技术进行了论述。
柔性墩中央索麵寬幅斜拉橋結構形式較為特殊，在主樑懸臂施工中對整體穩定、寬樑橫嚮抗扭、索力調整及不平衡荷載控製均有十分嚴格的要求。結閤浙江富暘鹿山大橋主橋上部結構，對獨柱式塔、單箱五室箱樑、多主桁長大掛籃、環氧鋼絞線斜拉索掛設、體繫轉換等關鍵施工技術進行瞭論述。

The structural form of flexible pier center plane cable stayed bridge is special. There are exacting requirements in multi?work situations of cantilever method construction, for instance, global stability , transverse anti?twisted abilities of wide?size box beam, adjusting the cable forces and controlling unbalanced load. Based on the superstructure of Lushan bridge, this paper introduced the key construction techniques in many aspects of single column tower, box girder, multi truss hanging basket, structure system transfer and so on.
