摘　　要：本文依托云南山区某人行绿道建设工程中一座外倾式不对称钢箱拱桥项目,通过有限元计算对外倾式不对称钢箱拱桥的典型受力特征和施工过程中关键控制问题进行分析说明,以达到为未来类似项目的建设提供设计和施工参考的目的。In this paper,an outward-inclined asymmetrical steel box arch bridge in a pedestrian greenway construction project in mountainous areas of Yunnan Province is analyzed and explained through finite element calculation of typical mechanical characteristics of outward-inclined asymmetrical steel box arch bridges and key control problems in the construction process,so as to provide reference for the design and construction of similar projects in the future.
