摘　　要：在市政交通工程建设中桥梁占有很重要的比例,其施工过程中的质量控制非常重要。从材料的选择到施工过程的质量控制,再到后期成品的保护和养护等,任何一个环节出现问题都会引起质量事故或质量缺陷。为尽量避免出现类似情况,笔者以锦江生态带现浇混凝土单拱桥施工为例,从基础稳定、桥台抗滑移、拱圈线性等控制重难点问题出发,阐述了对单拱混凝土桥梁施工控制要点进行的分析与研究,提出了具体的措施并予以应用,取得了较好的效果。Bridges occupy a very important proportion in the construction of municipal transportation projects,and quality control in the bridge construction process is very important.From the selection of materials to the quality control in the construction process,to the protection and maintenance of finished products,any problems in any link will cause quality accidents or defects.In order to avoid similar situation as much as possible,based on the construction experience of cast-in-place concrete single-arch bridge in Jinjiang Ecological Zone,The author expounds the control points of single-arch concrete bridge construction from the aspects of foundation stability,bridge abutment resistance,arch circle linearity,carries out analysis and research on key points,proposes and applies specific measures,and achieves good results.
