摘要
文章以成都轨道交通17号线机车厂站为例,对膨胀土地层地铁车站的深基坑快速施工技术进行研究。通过快速进行基坑开挖和钢支撑的架设,做好封闭隔水措施,确保围护结构变形可控,取得了较好效果,保证了基坑及周边建筑的安全。
Taking the Locomotive Factory Station of Chengdu Rail Transit Line 17 as an example,this paper studies the rapid construction technology of deep foundation pits at subway stations on the expansive land layer.Through the rapid excavation of the foundation pit and the erection of steel support,the sealing and water insulation measures are done to ensure that the deformation of the enclosure structure is controllable,good results are achieved,and the safety of the foundation pit and surrounding buildings are guaranteed.
