摘　　要：城市轨道交通盾构法隧道工程周边地表竖向位移控制指标是判断工程安全与否的重要依据。通过对我国多个城市50个工程实测案例的分析,研究了盾构法隧道工程周边地表变形的特点。根据隧道断面大小、场地地层条件等影响因素的分类,对地表竖向位移实测结果进行数理统计分析,给出了相应的建议控制值。The control index of vertical ground surface displacement in tunnel engineering with shield method for urban rail transit is the important basis for judging the engineering safety. According to the 50 actual cases analysis in some cities,the ground surface deformation characteristics surrounding the tunnel engineering with shield method is studied. According to the influence factors of tunnel section size and formation conditions and so on,this paper analyzes the measured results of vertical ground surface displacement,the suggested control values are given.
