| 摘 要： | 利用GPS的实时动态定位（RTK）技术进行打桩定位计算的理论与方法，主要通过建立相对于船体固定的船固坐标系统，并研究船固坐标与工程坐标相互转换的方法来实时计算设计高程面上桩中心的坐标，以及桩身的方位，采用在桩架上安装测距仪，建立桩架三维坐标系统并与船固坐标进行转换来测定桩与桩架的相对移动，最后通过实际工程应用验证了该模型的正确性．

| Abstract: | The principle and method regarding the positioning of sea piling engineering based on the(real) time kinematics of global position system technology(GPS-RTK) are discussed in this paper.The coordinate of picket center and the azimuth of the picket body are calculated in real time by establishing the ship-fixed coordinate system.In the meantime,the coordinate transform between the ship-root coordinate system and the engineer coordinate system is also studied.The distance measurement instruments used on the picket and the relative movements are determined by establishing the three-(dimension) coordinate system of picket,which is transformed from the ship-fixed coordinate system.Finally,the soundness of the model is validated by an engineering application case. |
