摘要
通过分析广东青岐涌特大桥特殊的桥位条件,工期要求等,得出了等高钢桁和变高钢桁两种主桥方案,对拟定的两种方案从安全、经济、体系结构、施工方法等方面做了研究比选,推荐采用变高钢桁混凝土组合连续刚构桥。
Through the analysis on equal altitude and constant altitude steel truss two main bridge schemes of special location situation, construction period requirement of Guangdong Qingqiyong super bridge, this paper made research and selection on proposed two schemes from safety, economy, system structure, construction method, recommended using constant altitude rigid truss concrete combination continuous rigid frame bridge.
