摘　　要：弯梁桥独特的弯扭耦合性质导致了它复杂的受力特性,这给工程设计带来了很大的不便。结合一座3×40m的预应力混凝土连续弯梁桥的工程设计,总结了该类桥型的设计要点,同时阐述了计算模型的选择和建立,并对不同的计算模型进行了对比分析,希望为同类型桥梁的设计提供一些参考。The curved beam bridge has a complex mechanical characteristic because of its unique nature of bending- torsional coupling , which will give engineering design tremendous inconvenience . The thesis combined engineering design of a 3× 40m - span prestressed concrete coontinuous curved beam bridge to summarize the key points of this type of bridge design and point out that how to select mathematical function and to construct calculation model at the same time . Finally , the various ways of calculation model were analyzed and compared to provide reference tO design of bridges of similar kind .
