大跨径组合梁桥移动悬索支架设计施工技术

Desi gn and Construction Technologies of Mobile Suspension Cable Support for Long-span Composite Girder Bridge

钢-混组合桥梁的设计施工方法灵活多变,适应性强,以某大跨连续钢-混组合箱梁桥为背景,提出移动悬索支架的设计施工综技术并进行了参数优化分析,结果显示,采用本技术可最大限度发挥出钢和混凝土两种材料的性能优势,有效提高大跨钢-混组合梁桥的经济性和适应性。

The design and construction methods of steel-concrete composite bridges are flexible,changeable and adaptable. Taking a long-span continuous steel-concrete composite box girder bridge as the background, the design and construction integrated technology of mobile suspension cable support is proposed, and the parameter optimization analysis is carried out. The results show that the use of the technology can give full play to the performance advantages of steel and concrete to the greatest extent,and effectively improve the economy and adaptability of long-span steel-concrete composite beam bridge.
