目前,我国经济建设项目日渐增多,重大项目规模逐步扩大。在交通工程建设领域,桥梁的施工规模也在不断增加,由于混凝土填充的钢管拱桥跨度大,质量良好,造型美观等优点,钢管混凝土拱桥日渐被用于特殊用途桥梁的建设。乌溪江大桥,作为浙江省内单跨最大的钢管混凝土拱桥,在建设过程中,得到了更多从业人员的关注,所以,针对大跨径钢管混凝土拱桥的施工分析和施工控制显得尤为重要。本文主要针对大跨径钢管混凝土拱桥施工控制的原理以及要求进行分析,提出施工的控制要点,希望能够提高该类桥梁的施工质量。
At present, the number of economic construction projects in our country is gradually increasing, and the scale of major projects is gradually expanding. In the field of traffic engineering construction, the construction scale of bridges is also increasing. Due to the advantages of large span, good quality and beautiful appearance of concrete-filled steel pipe arch bridges, CFST arch bridges are increasingly being used for the construction of special purpose bridges. As the largest CFST arch bridge with single span in Zhejiang Province, WuXiJiang Bridge has attracted more and more attentions from practitioners. Therefore, it is very important for the construction analysis and construction control of the large-span CFST arch bridge. In this paper, the principle and requirements of construction control of large-span CFST arch bridge are mainly analyzed, and the key points of construction control are put forward, hoping to improve the construction quality of such bridges.
