地铁精密水准控制网点布设于地铁沿线，由于施工影响和区域沉降影响，其点位高程难免会发生变化。本文提出了一种利用两期测量数据探测移动点并选择合理的、兼容的参考基准的方法。在等精度的前提下综合运用单点位移显著性检验和参考基准可靠性检验，最终得到合理、兼容的参考基准。并以此为基础编制程序，对实测数据进行了计算、分析。结果表明：该方法可以得到更合理、更兼容的参考基准。

The precision level control network of underground subway is located along the subway line, because of the influence of the construction and the regional settlement;it is inevitable that the height of the point will change.In this paper, a method for detecting moving point and selecting reasonable and compatible reference standard is presented in this paper.In the premise of equal accuracy of the use of a single point of displacement significance test and reference standards, and ultimately a reasonable and compatible refer-ence.And taking this as the basis, the data were calculated and analyzed.The results show that the proposed method can be more reasonable and more compatible.
