摘　　要：对于狭长的地铁隧道变形监测基准网,如何判断并确定稳定的基准点,是计算工作基点、变形监测点坐标以及进行变形分析的基础。针对目前常用的限差法的不足,该文将平均间隙法及t检验法应用于地铁隧道平面基准网的稳定性分析中,并通过实例分析,证明了该方法的有效性,可供类似变形监测工程数据处理借鉴。For deformation monitoring datum network of a narrow subway tunnel, how to judge and deter- mine the stable datum points is the basis of coordinates calculation for working points, deformation moni- toring points , and the analysis of deformation. Given the defects of the tolerance method commonly adopted currently, the paper proposed an approach based on the mean gap method and t test method to solve the problem of stability analysis for the horizontal datum network of subway tunnel. Through the ex- amples analysis, it verifies that the validity of method, which may provide reference for data processing in similar deformation monitoring engineering.
