| Abstract: | 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. |
