悬灌梁0#段施工是连续刚构桥梁重要承重结构,随着连续刚构桥梁跨度的不断增大,0#段体积也不断增大,施工技术更加复杂,若控制不好,会出现大量质量病害,影响施工和通车后正常使用。本文以重庆鱼洞长江大桥超大体积0#段施工为例,介绍了超大体积0#段施工技术,给出了确保0#段施工质量的关键技术及措施,对类似大跨度桥梁施工具有借鉴意义。 The construction of the cantilevered beam 0 # is an important load-bearing structure of the continuous rigid-frame bridge. With the continuous span of the continuous rigid frame bridge increasing, the volume of the section 0 # is also increasing. The construction technique is more complicated. If the control is not good, Quality of disease, affecting the normal operation after construction and opened to traffic. Taking the construction of super large volume 0 # of Chongqing Yuandong Yangtze River Bridge as an example, this paper introduces the construction technology of 0 # segment with super-large volume and gives the key technologies and measures to ensure the construction quality of 0 # segment, which is of reference significance to similar long-span bridge construction .
