摘要
在天津市海河综合开发起步工程基础设施建设中,为满足旧有桥梁通航净空的要求,成功地应用了同步顶升技术。该文在顶升施工完成后,分析了同步顶升技术在桥梁顶升工程中的应用原理及顶升过程中的一些关键问题,对此项技术在同类工程中的应用有较高的参考价值。
In order to meet the requirements of the navigational clearance of the old bridges, the synchronous jack-up technology is successfully applied in the construction of the infrastructures of Tianjin City Sea River Comprehensive Development Starting Project. After the completion of the jack-up construction, the article analyzes the application principle of the synchronous jack-up technology in the bridge jack-up works and some key problems in the course of the jack-up. The application of this technology has the higher value for reference in the similar projects.
