摘　　要：本文基于全站仪, 应用直接测量模型、 交会测量模型、 对某一变形点位进行观测.分析、 研究不同观测方法所得数据资料的质量和精度情况, 并讨论数据资料中观测误差的主要来源.最后比较两种不同观测方法的优、 缺点, 综合评判后找出最佳观测方法, 可为以后类似的测量工作提供一定的经验和依据.This paper based on the total station and used the direct measurement model, the intersection measurement model and the observation of a certain deformed point position. The quality and accuracy of data obtained from different observation methods were analyzed and studied, and the main sources of observation errors in the data were discussed. Finally, we compared the advantages and disadvantages of two different observation methods, and found out the best observation method after comprehensive evaluation,which will provide some experience and basis for similar measurement work in the future.
