摘要
以泉州湾跨海大桥A2标段主线桥上部箱梁工程实践为例,介绍大宽度变截面移动模架系统主要结构形式、受力特点及其关键施工技术的创新。实际工程应用证明,此类新型移动模架能满足大宽度变截面箱梁施工需要,对类似工程具有参考价值。
With engineering practice of upper box girders of main bridge at A2 section of Quanzhou Bay Oversea Bridge as an example, this paper introduces main structural forms, loading features of large-width variable cross-section mobile formworks system and innovation of key construction technologies. The practical engineering application proves such new mobile formworks can satisfy construction need of large-width variable cross-section box girders and exhibits reference value for similar projects.
