日新桥位于越南首都河内,横跨红河,是一座多塔结合梁斜拉桥。结合梁由钢工字形主梁及横梁与预制桥面板通过剪力钉连接而成。桥面板外侧安装风嘴以提高抗风稳定性。桥塔为A形钢筋混凝土结构。斜拉索采用平行钢丝索,扇形、双索面布置,桥塔端斜拉索锚固在钢锚箱上。下部结构采用钢管板桩沉井基础。根据桥址处实际条件及桥梁设计总体要求,通过多国规范的借鉴与应用,辅助以计算及试验研究,合理地确定多塔斜拉桥的结构总体设计参数,能够满足结构具体的功能要求及力学要求。
Located in Hanoi, capital of Vietnam, across the Red River, Nippombashi is a multi-tower combined cable-stayed bridge. The composite beam is made of steel I-shaped girders and beams and prefabricated bridge panels connected by shear nails. Outside the bridge deck to install the nozzle to improve wind stability. Bridge tower A-shaped reinforced concrete structure. Diagonal cable with parallel wire rope, fan-shaped, double cable surface arrangement, the tower cable-stayed tower anchorage in the steel anchor box. The lower structure of steel pipe sheet pile caisson foundation. According to the actual conditions of bridge site and overall design requirements of bridges, the overall design parameters of multi-tower cable-stayed bridges can be reasonably determined through the reference and application of multi-national norms to assist in calculation and experimental studies to meet the specific functional requirements and mechanics of structures Claim.
