摘　　要：研究异型拱桥的结构受力特征以及与正型拱桥的差别。通过计算实例 ,分析比较异型拱结构的力学特性 ,研究其吊杆斜率、矢跨比变化时引起的内力变化规律 。The mechanic characters of special-shape arch bridges and the contrast with the ordinary arch bridges are studied in this paper. Through numbering the examples, 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 the analysis, some conclusions have been obtained.
