摘　　要：以天津某交通枢纽深基坑工程为例,通过基坑开挖过程中周围地表竖向位移的实测资料分析,对比了基坑不同开挖方法下周围地表沉降的特点,总结了基坑开挖对周围地表沉降的影响因素,并提出控制沉降的措施.Based on the deep foundation project of a transportation hub in Tianjin,through the analysis of the actual testing data of the vertical displacement of surrounding ground during the excavation,this paper contrasts the ground settlement characteristics of different construction methods,and then analyzes the influencing factors of deep excavation on surrounding ground settlement,and finally puts forward the control measures of ground settlement.

关 键 词：逆作基坑 地表沉降 施工降水 附加荷载
