摘　　要：文章基于对广东省南围高架桥线位和周边环境的研究分析,充分考虑桥梁布跨与现状和远期市政道路之间的位置关系,选择桥梁设计标准和桥型方案,通过对城市高架桥各种影响因素的研究,最后选择造价合理、施工简单、景观好、后期维养简单的设计方案,标准段上部采用小箱梁,下部采用柱式墩+隐盖梁方案,跨被交路段上部采用连续箱梁,下部采用分肢花瓶墩方案。Based on the research and analysis of the line position and surrounding environment of Nanwei viaduct in Guangdong Province, this paper fully considers the positional relationship between the bridge span and the current situation and the long-term municipal roads, and selects the bridge design standard and bridge type scheme. Through the study on various influencing factors of urban viaducts, the design scheme with reasonable cost, simple construction,good landscape and simple maintenance in the later stage is finally selected. The upper part of the standard section adopts small box girder, the lower part adopts column pier + concealed capping girder scheme, the upper part of the crossing section adopts continuous box girder, and the lower part adopts split vase pier scheme.
