摘　　要：湖里大道立交桥为预应力曲线斜腿连续刚构系杆拱桥 ,针对其施工特点 ,进行了施工过程三维有限元分析 ,对原设计提出了若干改进意见。Huli grade separation bridge is a prestressed curved continuous rigid frame tied arch bridge with indined legs. According to its construction characteristics, three dimensional finite element analysis is carried out, and some proposals for improvement are presented in detail. The analysis has the reference value for the similar projects.
