摘要

钢—混凝土连续组合梁桥具有自重轻、抗扭能力强、刚度大、施工速度快的优点,结合南京大桥北路匝道桥,介绍了组合梁在城市高架中的设计与应用,通过调整桥面板混凝土浇注顺序,中支点顶升20cm,有效控制了负弯矩区域混凝土桥面板的开裂。
        The steel-concrete continuous composite beam bridge is with merits of light self weight,strong torsion resistance ability,large rigidity,and rapid construction speed. In combination with the ramp bridge at north road of Nanjing bridge,the design and application of composite beams in urban overhead viaduct are introduced.The central bearing point is lifted 20 cm by adjusting the concrete pouring sequence of bridge deck slab,so as to effectively control the crack of concrete bridge deck slab in the area of hogging moment.
