大跨预应力混凝土连续梁桥设计研究

Study on Design of Long-span Prestressed Concrete Continuous Beam Bridge

结合某(60+105+60)m预应力混凝土变截面连续箱梁桥设计,对大跨径预应力混凝土变高度连续箱梁桥截面形式的选取、结构尺寸的拟定、预应力钢束布置方式等设计要点进行了研究分析,可供同类桥梁结构设计进行参考。

Combined with the design of a(60+105+60)-m prestressed concrete variable cross-section continuous box girder bridge, the article studies and analyzes the design gist to select the section form, to propose the structural dimensions, and to arrange the prestressed steel strands of the long-span prestressed concrete variable cross-section continuous box girder bridge, which can be referred for the structural design of the similar bridges.
