新型模板体系在变截面现浇箱梁施工中的应用

摘要

The cast-in-situ box girder construction of non navigable span, which is in the joint part of island and bridge on the east island of Hongkong-Zhuhai-Macao Bridge, is operated in marine, with high security risk. The curve of the box girder is large, and the construction has high requirements, short period, and huge difficulty. The adoption of new type of formwork technology has significantly enhanced the construction schedule, quality and safety of the cast-in-situ box girder. The paper can supply references for the similar projects.%港珠澳大桥东人工岛岛桥结合部非通航孔桥现浇箱梁施工属于海上作业，安全风险高，箱梁曲线弧度大，施工要求高，工期短，难度大。通过采用新型模板体系，显著提高了现浇箱梁的施工进度、质量和安全，可为类似工程参考。
