针对高速公路上立交匝道桥在平面上的较小半径特征,利用平面网格对高速公路上一2×35m现浇预应力混凝土连续弯箱梁的设计进行优化分析,以了解立交匝道弯桥与直桥的受力差别,为同类型桥梁提供借鉴。
In view of the small radius characteristic of the freeway ramp bridge in the plane, the design of a 2 × 35m cast-in-place prestressed concrete continuous curved box girder bridge on expressway is optimized by plane grid to understand the relationship between the on-ramp bridge and The difference of force of straight bridge provides the reference for the same kind of bridge.
