摘要
以一座公路混凝土槽形梁跨线桥为背景,研究了公路混凝土槽形梁横向加劲行车道板和端横梁的设计计算方法,针对边梁纵向预应力钢束可能引起的梁端附近行车道板中较大横向拉应力,提出了相应地设计改善措施。
Based on a highway concrete U-shapeoverpass bridge,the design and calculation method of the bridge deck with transverse stiffener andthe end cross beam were studied. Design method and improvement measures were put forward for the problem of large transverse stress near the end cross beam caused by the longitudinal prestressed tendons.
