预应力混凝土连续梁匝道桥计算分析

Calculation and Analysis of Prestressed Concrete Continuous Ramp Bridge

结合京藏高速公路海石湾收费站连接道路,王家口互通式立交E匝道4×30m预应力混凝土连续箱梁设计过程,简要分析了曲线匝道桥梁的分析过程,给出了主要的设计计算方法。

Combined with the design process of 4×30m prestressed concrete continuous box girder for the connecting road of Haishiwan toll station of Beijing-Tibet Expressway and the 4×30m prestressed concrete continuous box girder of the interchange interchange,the analysis process of the curved ramp bridge is briefly analyzed,and the main design calculation method is given.
