摘　　要：为探讨大型桥梁工程主拱座施工技术,文章结合重庆市武隆区龙溪乌江大桥实际情况,立足主拱座施工重难点,分析了主拱座混凝土裂缝的成因,并提出主拱座施工技术的应用要点和注意事项。研究表明,主拱座是组成大型桥梁工程的主要结构,其施工质量直接关系桥梁工程结构的稳定性、实际安全使用寿命。混凝土裂缝是主拱座施工质量的主要影响因素,在具体施工中,需要结合工程特点,严格把控主拱座每道工序的施工质量,最大限度地保证主拱座施工,创建高质量、高品质的大型桥梁工程。In order to explore the construction technology of the main arch support in large bridge engineering,combined with the actual situation of Longxi Wujiang Bridge in Wulong District of Chongqing,based on the key and difficult points of the main arch support construction,the causes of concrete cracks in the main arch support are analyzed,and the key application points and precautions of the main arch support construction technology are put forward.The research shows that the main arch support is the main structure of large bridge engineering,and its construction quality is directly related to the stability and actual safe service life of bridge engineering structure.Concrete cracks are the main influencing factors of the construction quality of the main arch support.In the specific construction,it is necessary to strictly control the construction quality of each procedure of the main arch support in combination with the engineering characteristics,so as to ensure the construction of the main arch support to the maximum extent and create high-quality large bridge engineering.
