兴凌线小赵屯钢混组合桥梁施工技术研究

Study on Construction Technology of Xiaozhaotun Steel-concrete Composite Bridge on Xingling Line

以兴凌线小赵屯钢混组合桥梁为研究对象,研究钢板梁在辽宁省中小跨径桥梁中的推广应用。结果表明,钢混组合桥梁可以充分发挥钢结构桥梁的性能优势,综合考虑公路桥梁全寿命周期管理成本、安全耐久性,可以有序推进我省中小跨径钢混组合梁桥的建设,不断提高新建、改扩建公路建设项目钢结构桥梁应用比例。

Taking Xiaozhaotun steel-concrete composite bridge of Xingling Line as the research object,this article studies the application of steel plate girder in medium and small span bridges in Liaoning province.The results show that steel-concrete composite bridges can give full play to the performance advantages of steel structure bridges.Considering the cost of life cycle management and safety and durability of highway bridges,they can promote the construction of small and medium span steel-concrete composite bridges in our province in an orderly way,and continuously improve the application proportion of steel structure bridges in newly-built,rebuilt and expanded highway construction projects.
