摘　　要：城市地铁控制网是变形监测的基准,其稳定与否直接关系地铁的运营安全。对平均间隙法进行改进并结合南京地铁一号线新模范马路车站地铁隧道变形监测实例,利用两期观测数据对平面控制网进行稳定性分析,就狭长区域平面控制网稳定性的检验等有关问题进行探讨,为地铁的运营提供了科学的保证。The control network of urban subway is the benchmark of deformation monitoring, its stability directly affects the safety of subway operation. Here, through the improvement of the mean gap method, the stability of plane control network is analyzed by using two periods of observation data combined with the deformation monitoring example for the subway tunnel of Xinmofan Road Station in Nanjing Subway No. 1 Line, and the problems such as the stability test of the plane control network in long and narrow area and so on are discussed, which could provide a scientific guarantee for the subway operation.
