摘　　要：对西安地铁1号线朝阳门站—康复路站区间湿陷性黄土暗挖隧道的施工风险及控制措施进行了探讨,重点分析了饱和软黄土失水引起的地层固结沉降、周边建筑物沉降变形、地下管线破坏、开挖过程中引起的变形等。根据湿陷性黄土的特性及风险特征,提出了饱和软黄土失水固结沉降风险的应对措施和隧道开挖土层变形沉降风险的应对措施,以及其它一些关键技术的控制措施等。Through an introduction of the construction risk and control measures of the Chaoyangmen-Kangfulu section on Xi＇an Metro Line 1, which passes the collapsible loess, the stratum consolidated settlement, the ground settlement and deformation of the surrounding buildings caused by the saturated soft loess dehydration, and damage of underground pipeline caused by the excavation are analyzed. According to the characteristics of collapsible loess and the engineering risks, some counter measures, including the consolidation settlement risk control, the dehydration of saturated soft loess, the excavation soil deformation sedimentation control, and other key technologies are proposed.
