摘要
为解决海上打桩过程中用全站仪进行圆桩放样问题,通过观测圆桩同一水平面上桩身一点三维坐标和桩侧面切线一个方向,建立切线坐标系统以及椭圆坐标系统模型,并根据观测量之间的相互制约关系,实现圆桩中心坐标的解算。对现场实测数据的计算验证了该算法的所能达到的精度和模型的有效性。
Up to now,there are no sophisticated and effective methods of circle pile position in piling engineering.A concise,stable and reliable algorithm to position circle pile is introduced,which is surveying one 3D point coordinate on pile surface and one tangent direction of pile side in the same level.The tangent coordinate system and ellipse coordinate system were built in this position model.According to the restraint relationship between the measurements,the coordinate of circle pile center can be obtain.At last,the achievable accuracy of this algorithm is analyzed.The field test data and calculated results verifly the correctness of this algorithm.
