摘　　要：文章以某立交匝道桥改造工程为例,通过对墩柱接高和盖梁改造设计、施工的重难点分析、结构体系转换的理论计算,提出了合理的设计方案。施工实践及监控量测表明,该设计方案及施工工艺安全、可靠。Taking an interchange ramp bridge reconstruction project for example,through heighten the piers and remould-designing of the bridge bent cap,analysis of construction diffficuhies,and theoretical calculation of structure system transformation, a reasonable design scheme was proposed. Combined with the construction practices and monitoring measurement,it indicated the design proposal and construction craft are safe and reliable.
