摘　　要：桥梁工程项目建设中,原材料的质量对整个工程项目建设的质量会产生重要影响。Q460高强度钢在双跨连续梁结构的整体构建施工中具有重要作用。双跨连续梁施工建设的设计环节、施工中的数据计算环节以及施工建设时关于荷载与位移之间的关系研究,都是Q460钢材结构在应用时需要研究的重点。只有从前期的设计到中期的实践应用都进行有效规划,提升Q460钢结构的应用稳定性,才能够发挥此类钢结构在连续梁施工建设中的积极作用。此外,Q460钢双跨连续梁的稳定性能测试需要结合不同的参数指标合理规划,有序推进。In the construction of bridge projects, the quality of raw materials will have a very important impact on the quality of the whole project construction. Q460 high-strength steel plays a very important role in the overall construction of double span continuous beam structure. The design link of double span continuous beam construction, the data calculation link in construction and the research on the relationship between load and displacement during construction are all the key issues to be studied in the application of Q460 steel structure. Only when the application stability of Q460 steel structure can be improved through effective planning and operation from the early design to the mid-term practical application, can such steel structure play a positive role in the construction of continuous beam. The stability performance test needs to be reasonably planned and orderly promoted in combination with different parameter indicators.
