数字水准仪与光学水准仪的测量精度比较

Survey accuracy comparison of digital level and optical level

几何水准测量对整个国家范围内的高精度水准网的布设来说,其精度高但其效率低,为了提高精密水准测量的作业效率,本文在河南理工大学校园内设计了一个闭合水准路线进行实地水准测量,通过计算对二者的测量精度进行比较,根据它们达到的精度指标来比较各自的优劣,进而在以后的实际工作中可以根据实际需要来选择合适的仪器来进行测量。

For the high-precision leveling network layout within entire country, geometric standard of measurement has high accuracy and low efficiency. In order to improve the efficiency of precise measurement, this paper designs a closed leveling line in Henan polytechnic university campus. The measure precision of two levels is compared.
