摘　　要：对北京地区72个城市轨道交通矿山法隧道工程实测案例进行分析,研究了矿山法车站、大断面区间隧道以及标准断面区间隧道的地表变形特点。根据地层条件的不同,对砂卵石地层和黏性土地层的地表沉降实测结果分别进行数理统计分析,提出了地表变形控制的建议数值。研究成果对北京及地质条件相似地区的城市轨道交通矿山法隧道工程地表变形大小预测、监测控制标准确定以及安全风险管理等具有重要的指导作用。Based on the 72 actual measurement cases analysis of urban rail transit with mine method for tunnel engineering in Beijing, the ground settlement characteristic of station, large section tunnel and standard section tunnel are studied. According to the stratum conditions, the statistical analysis for measured results of ground settlement are done in sand ＆amp; gravel strata and cohesive soil strata. The proposed values of ground deformation control are suggested. The research achievement may give important guides to the ground deformation prediction of urban rail transit with mine method for tunnel engineering . It has a guidance for the monitoring controlled standard determination and the safety and risk management in Beijing and similar geological condition area.
