摘要:

为摸索出适用于城市交通繁忙、不易立尺地段的地表沉降观测新方法,通过推导全站仪固定测站三角高程测量精度公式,论证用三角高程测量可满足二等水准测量,并根据大量的实测数据以及采用全站仪三角高程法与NA2水准仪法结果对比分析,得出采用全站仪固定测站的方法,可满足城市闹市区交通繁忙市政道路的地表沉降观测,该方法值得借鉴和推广。

Abstract:

The theoretical basis for the conclusion that trigonometric leveling can meet the requirements of grade II leveling survey is expounded by deducting the accuracy formula of the trigonometric leveling with fixed total station monitoring points, so as to find a new ground surface settlement monitoring method in busy urban areas where conventional measurement is difficult. The large amount of the measurement data and the comparison and contrast between the monitoring results of the trigonometric leveling with total stations and those of NA2 leveling demonstrate that the method of fixed total station monitoring points can meet the requirements of the ground surface settlement monitoring in busy urban area and is worth to be popularized.

Key words: total station, fixed monitoring point, trigonometric leveling, ground surface settlement monitoring
