摘　　要：拱梁组合体系桥梁的结构具有复杂的受力特征和多样的外形特征。复杂的受力特征决定了各拱梁组合体系桥梁的设计细节不同,多样的外形特征使此类桥型可适用于各种环境。本文通过对两座拱梁组合体系桥梁设计的比较和分析,直观地反映了此类桥梁设计中拱梁刚度比的决定性影响;同时分析了两桥在拱肋、系杆等细节的不同设计方法。The structure of beam-arch combination system bridge has complex mechanic characteristics and various appearance characteristics. The complex mechanic characteristics determine the difference of the beamarch combination system bridge design detail and the various appearance characteristics can make this kind of bridge suitable to various environment. By analysis and comparison on the design of two beam-arch combination system bridges, this paper reflects the decisive influence of stiffness ratios of arch to beam in this kind of bridge design directly, and analyzes different design methods of these two bridge on arch rib tie bolt, and other key points for these two kinds of bindges.
