全站仪高程测量方法研究与实践

Research and Practice on Total Station Elevation Measurement

从高程测量方法及误差传播原理出发,介绍了采用全站仪代替水准仪进行高程测量的方式方法,并用全站仪对某个高程控制网点进行实测高差数据与几何水准测量的数据进行比较,得到的全站仪高程测量中误差在四等水准限差范围内,证明了在一定范围内用全站仪代替水准仪进行高程测量可达到四等水准测量的精度要求。

Based on the method of elevation surveying and the principle of error propagation,this paper introduces the mode and method of elevation surveying using a total station instrument instead of a level gauge.Comparing the height difference data of a certain elevation control network using total station and the data obtained using geometric leveling,it is concluded that the mean square error in total station leveling is within the range of fourth order leveling tolerance,and it is proved that the fourth order leveling error tolerance can be reached using total station elevation measurement.
