| 摘 要： | 近年来,在高精度水准测量领域数字水准仪逐渐呈现出取代光学水准仪的趋势。本文通过实际观测实验,对比分析了两类水准仪的优势与不足。结果表明,光学水准仪相对较重,但性能稳定,而数字水准仪轻巧、操作方便,能很好地避免人为读数误差。在实际工作效率上光学水准仪占优,测量精度的稳定性好于数字水准仪。

| Abstract: | In recent years, it has a tendency to use digital leveling instrument to replace the optical leveling one in the field for high-precision digital leveling survey. In this paper we conducted a comparative analysis of the two types of leveling in both advantages and disadvantages. The results show that the optical leveling instrument is relatively heavy, but stable, while the digital one is light in weight, easy to operate, and can avoid human error well in surveying. In practice, the optical leveling is dominant due to high efficiency of work and more stable measurement. |
