摘　　要：预应力混凝土鱼腹式连续梁桥造型美观、受力合理,且相对于常规箱梁而言桥下净空更大,因而在城市桥梁中已获得广泛应用。以一座鱼腹式箱梁桥为例,介绍了上部结构的设计与计算分析,总结了不同荷载状态下结构应力的基本要求。Much attention is devoted to prestressed concrete continuous fish-bellied box-girder bridge for its advantages,such as attractive appearance,uniform stress,reasonable headroom,which makes it popular in the municipal engineering. The analysis and design method of the super-structure is introduced and stress distribution under different loads is presented. The research results can be a reference for similar bridge.
