| 摘 要： | 拟稳平差是一种顾及基准点稳定性的平差方法，在变形监测领域有着广泛的应用。介绍了拟稳平差的基本原理，说明了拟稳平差在沉降观测中的应用；拟稳平差的关键是选取符合实际的“拟稳点”，讨论了拟口点选择的两种方法：假设检验法和模糊聚类法，并给出算例进行说明。

| Abstract: | Quasi-stable adjustment is an adjustment method taking the stability of datum points into account, which is widely applied in the field of deformation monitoring. This paper introduces the basic principle of quasi-stable adjustment, and illustrates the application of quasi-stable adjustment to the settlement observation. The key of quasi-stable adjustment is to select quasi-stable points correctly. The paper discusses two methods to select quasi-stable points: hypothesis tests and fuzzy clustering. |
