摘　　要：跨线桥的使用状况对交通通畅、经济效益产生巨大的影响,跨线桥应符合寿命长、低维护、全寿命成本低的要求。因此,文章认为要从桥梁的规划、设计、施工、运营管理、检测评定、养护维修,直到拆除和材料回收再利用的全过程进行分析研究,贯彻桥梁全寿命周期成本的设计理念。因此,有必要对跨线桥常见桥型的全寿命成本进行研究,指导今后同类桥梁的建设。The use of overpasses has a significant impact on traffic flow and economic benefits.Overpass bridges should meet the requirements of long service life,low maintenance and low full life cost.Therefore,the article argues that the analysis and research should be conducted from the entire process of bridge planning,design,construction,operation management,testing and evaluation,maintenance and repair,to demolition and material recycling and reuse,to implement the design concept of life-cycle cost of bridges.Therefore,it is necessary to study life-cycle cost analysis of common bridge types of overpass bridges and guide the construction of similar bridges in the future.
