摘要
九天湖大桥是一座建设在软土地基上的三跨连续梁拱组合桥,该文论述了在结构分析建模时考虑到桩基的柔度,采用模拟双柱式基础,结果表明软土地基对结构受力有利。文章还阐述了该组合桥的施工特色和施工监控,并通过施工过程中的应力监测验证了分析的正确性和后浇带设置的优越性。
Jiutian Lake Bridge is a 3-span continuous beam arch composite bridge built on the soft soil subgrade. The article discusses the flexibleness of pile foundation considered and the simulated double-column foundation used when the model is built for the structural analysis. The result makes clearly that the soft soil subgrade is favourable for the structure bearing. The article also sets forth the construction characteristics and construction monitoring of this composite bridge, and verifies the analyzing correction and superiority of post-poured belt installation through the stress monitoring in the course of construction.
