| 摘 要： | 根据全站仪三角高程测量的原理和方法,在平原微丘区的地形上,对一条附合水准路线分别进行全站仪三角高程测量和水准仪四等水准测量,应用误差传播定律对两者的测量精度进行了对比分析。结果表明,全站仪的测量精度略高于水准仪的测量精度,且使用较方便,受地形限制小,作业效率高,故全站仪三角高程测量可以代替四等水准测量。

| Abstract: | According to trigonal height measurement principles and methods in plain and slight high terrain, measures an annexed leveling line respectively by means of trigonal height measurement and four-grade-leveling measurement, applies error propagation law to the system analysis and compares the measurement accuracy. The results show that the measuring accuracy of total station instrument is slightly higher than that of leveling instrument, and convenient for use, small restricted by topography and high work efficiency, so the trigonal height measurement can replace four-grade-leveling measurement. |
