摘要
针对大跨度预应力混凝土箱梁桥,探讨了其截面尺寸的拟定、边界条件的确定、预应力筋布置形式、预应力张拉应力的控制及截面抗剪设计。
In the light of a long-span prestressed concrete box girder bridge,this paper probes into the determination of the sectional dimension and boundary condition,the layout form of prestressed reinforcement,the control of prestressed tensile stress and the design of section shear strength.
