摘　　要：　应用测量误差传播定律,通过分析点位误差及在任意方向上的位差,导出用全站仪极坐标法进行桥墩台中心定位的精度估算公式,据此可选择满足限差要求的全站仪进行桥梁墩台中心定位放样。With law of transmission of surveying accuracy error, and analysis on the related errors between points and at the free direction, the equation of accuracy estimation is derived by using the radial coordinates with total station in this article, and it can be used for centering the piers and abutments by selecting a total station which can meet the requirements of error limit.;
