新技术应用于厦门环岛路A标工程

New Technique in the Project of Contract A of Xiamen Around-the-Island Road

针对新技术在厦门环岛路A标工程的成功应用,介绍了箱梁—墩柱—灌注桩竖向预应力结构体系的施工技术、后张法预应力孔道真空压浆技术、海中低标高桥梁的现浇箱梁的设计与施工技术等。工程的实践证明:各项新技术、新材料的应用是成功的。为今后类似的工程施工或单项技术工艺的应用提供了借鉴。

In view of a successful application of new technique in the project of contract A of Xiamen Around-the- Island Road, the paper introduces the construction techniques of box girder-pier column-cast-in-situ pile vertical prestressed structural system, the technique of vacuum grout jacking in post-tensioned pretressing channel and the design and construction techniques of cast-in-situ box girder of low-elevation bridges on sea. The practice of project has demonstrated that the application of new techniques and new materials is successful and it provides an experience for the construction of similar works and the application of single technique in future.
