【摘要】 鱼脊连续梁桥是一种截面形式比较特殊的梁桥,由梁体与鱼脊立墙组成。鱼脊立墙作为鱼脊桥梁的主要构件,不但承担着桥梁景观功能,同时也为大跨径桥梁提供了大部分的结构刚度,贡献了桥梁主要的竖向承载能力。结合两港公路大治河桥主桥——国内首座下承式特大型宽桥面混凝土鱼脊连续梁桥,介绍鱼脊立墙内的超高差、超长、超大吨位预应力钢束施工关键技术的研究。更多还原

【Abstract】 Fin-back continuous beam bridge is a beam bridge with special section forms,composed of beam body and fin-back vertical wall.As the main bridge components,the fin-back vertical wall is not only bearing the bridge landscape functions,but also is providing more structural rigidity and the main vertical bearing capacity for large span bridges.The construction key technologies of super elevation,super long & super large tonnage of prestressed steel strand are studied,based on the Dazhihe River Bridge on Lianggang Highway:the first through extra-large concrete fin-back continuous beam bridge with wide deck in China.更多还原
