| 摘 要： | 对于施工周期较长的大型工程，通常需要对控制网进行定期复测和稳定性分析。控制网复测期间，有时会遇到点位破坏或增设新点等情况，从而使两期控制网的网形不一致。针对控制网无固定起算点和网形改变的问题，讨论控制网的稳定性分析方法，并进行实例分析，为控制网的正确使用提供重要保证。

| Abstract: | It＇s necessary to regularly remeasure and analyse the stability of control network when the project has long construction cycle and large scale. During the period of remeasuring, some control points may be destroyed or some are added , which lead to a change in network configuration. A method of stability analysis is discussed and an example is given to deal with the problem that the control network has no immovable point and its configuration changes, which provides an important guarantee to the proper use of the control network. |
