摘　　要：针对某三跨变截面双塔单索面预应力混凝土矮塔斜拉桥进行研究,考虑了不同合龙高差下,强迫合龙对桥梁成桥后整体挠度和内力的影响,分析各合龙高差下桥梁整体线形和内力的差异,为类似桥梁施工提供参考的依据。The paper aimed at certain three-span variable section cross-section twin pylons and single cable plane prestressed concrete low-pylon cable-stayed bridge to conduct study,considering under different closure height difference,the influence of forced closure on entire deflection and internal force after the bridge completed,the difference of bridge entire alignment and internal force under every closure height difference were analyzed,which can provide reference for the similar bridge construction.
