摘要
结合现有钢桁架拱梁组合体系桥梁资料,对其总体设计中的拱肋桁架布置形式、拱轴线的选取、矢跨比、拱顶和拱脚高度的选择、杆件截面形式、桁架节点的构造等方面进行了研究和比对。
The paper discusses following aspects of steel trussed arch-beam bridge overall design： layout of arch rib truss, arch axial cord, ratio of rise to span, definition of arch crown and spring, section form and joint constitution.
