摘　　要： 本文通过刚构-连续组合梁桥与连续梁桥和连续刚构梁桥的综合对比分析,结合某座大跨径 预应力混凝土刚构-连续组合梁桥的模型试验和实桥荷栽试验,探讨了大跨径预应力混凝土刚构-连 续梁桥的力学特点和使用性能,对于完善大跨径刚构-连续组合梁桥的设计理论、指导工程施工,确保 结构安全、设计合理等方面都具有重要的参考价值。 On the base of test of plexiglass model and the loading test of a large-span prestressed concrete bridge with rigid frame-continuous structure, differences between the bridge with rigid frame-continuous girders and continuous bridge and continuous rigid frame bridge are compared and analysed. The force characteristics and structural behaior of large-span prestressed concrete bridges with rigid frame-continuous structure are studied. It offers an important reference to the perfection for design theory and construction technology of large-span prestressed concrete bridge with rigid frame - continuous girders.
