摘　　要：大亚湾某工程为30万t级外海高桩墩台原油码头,水上共18个墩台,其中16个墩台采用钢管桩基础。该地区常年潮差较大,波高浪急,台风频袭。结合该工程,介绍GPS-RTK打桩定位系统在沉桩施工的应用和沉桩工作流程,详细推导出船固坐标与施工坐标的转换关系。There are 18 dolphens in total for a piled crude oil jetty for 300 000 DWT tankers in Dayaowan Gulf, out of which 16 dolphens are built on steel tubular piles. In this region, the perennial tidal range is great with high waves and rapid swells as well as frequent typhoons. The application of the GPS-RTK Pile Positioning System for piling for the project and the pile driving procedures are described and the conversion of the ship fixation coordinates to the construction coordinates is also derived.
