  要:应用三角高程进行沉降监测时,很多同志过分依赖于精密仪器的高精度,虽然也完成了监测任务,但在理论上不严密,监测结果存在不稳定因素。本文从点位设置、观测方法等方面入手,阐述了消减系统误差的测量方法,并系统、定量的分析了单向三角高程沉降监测误差的产生、传播规律,并提出了对沉降量中误差进行预判,变事后误差的被动控制为事前主动控制的方法,供大家参考。

Abstract: when applying trigonometric leveling to subsidence monitoring, many comrades depend too much on the precision of precision instruments. Although they have completed the monitoring tasks, they are not rigorous in theory, and there are unstable factors in the monitoring results. This paper starts from the point set, observation method and other aspects, expounds the measuring method of abatement system error, and the systematic and quantitative analysis of the propagation law of unilateral                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  triangulation settlement monitoring error, error of the proposed settlement in anticipation, passive control after the change of error method for active control in advance for your reference.
