摘要
介绍水准支点测量的方法,根据水准支点观测的特点,从影响水准测量精度的仪器误差、外界因素误差和观测误差3方面对水准支点的误差进行分析,计算i角和大气折光产生的误差的大小,并提出减弱或消除这些误差的措施。
This paper introduces the measuring method of leveling branch point. According to the characteristics of the observation of leveling branch point, the errors of leveling branch point are analyzed from three aspects including instrument error, the error brought outside factor and observation error. At last,The errors of i angle and atmosphere refraction are calulated, and some methods of weakening or eliminating these errors are
