海上桥梁施工平台的搭建技术

Erection Techniques of Construction Platforms for Bridges over Sea

借鉴海上石油钻井平台和江河桥梁施工平台的经验,根据海上桥梁墩位所处海域水文情况、基础形式及大型专用设备配备条件,介绍海上合理选择诸如插桩平联法、护筒支撑法、导管围堰法、浮箱法等施工平台的形式及平台的关键施工技术,对海上特大型桥梁建设顺利进行具有一定意义。

With reference to experiences of offshore drilling platforms and construction platforms for bridges over rivers, and in accordance with the hydrologic conditions at pier sites of bridges over sea, their foundation types and large purpose-made equipment available, this paper describes the reasonable selection of the types of the construction platforms for the bridges over sea and key construction techniques for erection of the platforms, such as piling and lateral bracing method, steel casing supporting method; duct and cofferdam method and floating tank method. The appropriate selection and erection techniques for the platforms are significant to the smooth proceeding of the construction of the bridges over sea.
