| 摘 要： | 钢管混凝土拉索拱桥是在"桁式组合拱桥"的基础上将钢管混凝土拱桥、桁架拱桥、斜拉桥的技术特点综合起来,扬长避短,而构思出的一种新桥型。通过对全桥在恒载作用下变形和内力的分析研究,得出了该桥型的基本特点是以钢管混凝土拱肋受力为主的结构体系。

| Abstract: | The cable-supported concrete-filled steel tube arch bridge is a new bridge type developed on the basis of the truss type hybrid arch bridge by combining various techniques and making full advantages of the concrete-filled steel tube arch bridge,truss arch bridge and cable-stayed bridge.In this paper,through analytic study of the deformation and internal forces of the overall cable-supported concrete-filled steel tube arch bridge under the action of dead load,the basic feature of the bridge has been obtained,that is,the bridge is a kind of structural system with its concrete-filled steel tube arch ribs working as the major carrying components. |
