摘　　要：针对近年出现的一种新型的拱结构———异型拱桥,从美学观点探讨了其造型特点,论述了其用于城市桥梁的可行性,结合有限元数值计算分析了其受力特性,研究了其在吊杆斜率、矢跨比变化时引起的内力变化规律,得出一些有益的结论。综合美学特征讨论了其用于桥梁结构的工程实践,对推动结构学与建筑学的结合有一定的推广作用。From the point of aesthetic,the characters of a specialshape arch bridge and it's feasibility using in the city bridges are discussed.Its mechanics characters has been studied through numbering the examples with finite element program.Also,the variety law of specialshape arch bridge's internal force is analyzed when the suspenders slope and the risespan ratio are changed.In the light of analysis,some conclusions are obtained.The bridge construction considered the aesthetics purpose is valuable in the combination of structure engineering and architectonics.
