两跨连续梁桥在实际桥梁工程项目中,采用的概率相对较小,其经济指标相对于多跨连续梁桥要低一些。以舟山市小干二桥工程引桥中间某联2×36 m预应力混凝土连续箱梁桥为背景,从主梁设计准则、主梁构造尺寸拟定、主梁钢束配置及纵向计算等方面,对其主梁设计及纵向计算进行深入介绍,可为类似工程项目提供有益的参考。
Two-span continuous beam bridge in the actual bridge project, the probability of using relatively small, its economic indicators relative to the multi-span continuous beam bridge to be lower. Taking the 2 × 36 m prestressed concrete continuous box girder bridge in the middle of the approach bridge of Xiaogan No.2 Bridge in Zhoushan City as the background, this paper analyzes the main girder design criteria, main girder structure size, main beam girder configuration and longitudinal calculation, Beam design and longitudinal calculation in-depth introduction, for similar projects provide a useful reference.
