摘要
全站仪已广泛用于土木工程测量实践中。本文根据全站仪对向观测三角高程测量的原理，对其高差精度进行了分析，阐述了在一定范围内可用上述测量方法代替三、四等水准测量的见解。
Total Station Optical Electronie Tachometer widely applied in civil engineering surveying. According to the theory of trigonometric leveling of the Total Station Optical Electronic Tachorneter double-direction observation, the paper analyzes its precision of height difference. It puts forward that above-mentioned surveying method may replace third class and fourth -class leveling in certain range.
