| 摘 要： | 对高程控制网进行周期性观测，其点位差异是由观测误差所引起，还是点位真正的沉降，必须对它们进行区分，这就是点位稳定性分析问题。本文简要介绍了高程控制网整体稳定性分析的平均间隙法，详细介绍了单点位稳定性的间隙分块法和t检验法，并结合具体的实例，分别采用了间隙分块法和t检验法对高程控制网中的点位进行了稳定性分析，并对分析的结果进行了详细的对比，证明了这两种方法都是行之有效的。

| Abstract: | When the height control network is observed periodically, whether the point difference is caused by the observation error or is really subsident must be distinguished. This paper briefly introduces an average spacing method of the whole stability of the height control network and also present.s spacing block method and t test method of the single - point stability of the height control network. In addition, with specific examples, it analyzes the point stability of height control network based on spacing block method and t test method. The resuh shows that the two methods are effective. |
