五跨连续钢管混凝土系杆拱桥施工加载程序优化

以潮州市韩江北桥(五连跨钢管混凝土拱桥)施工为例,提出在坚持基本对称加载的原则下通过计算分析论证,对施工加载程序进行优化调整的方案。计算表明该优化缩短了工期,具有明显的社会效益和经济效益,对同类桥梁的施工有较好的借鉴作用。

Optimization of Construction Loading Procedures for Five-Span Continuous Concrete-Filled Steel Tube Tied Arch Bridge

Taking the construction of the North Hanjiang River Bridge(a five-span continuous concrete-filled steel tube tied arch bridge) in Chaozhou City as an example,this paper proposes the solution for optimization and adjustment of construction loading procedures for the type of the bridge through calculation and analysis verification on the principle of maintaining that the loading should be basically symmetric.The calculation shows that the solution proposed in the paper can shorten the construction time schedule,is of significant social and economic benefits and is also of good reference value to the construction of similar bridges.
