摘　　要：文章结合工程实例,基于工程基本情况和工程水文地质情况,给出一系列深基坑施工过程管控措施,通过基坑变形监测明确深基坑施工对临近地铁线路的影响,在此基础上进行基坑边坡支护方案比选,然后依次开展支护桩施工、土方开挖、主体桩基施工以及土方回填过程的管控,所得的成果可为类似工程提供借鉴和参考。Combined with the engineering example,based on the engineering basic situation and hydrogeological situation,this paper gives a series of control measures for the construction process of the deep foundation pit.Through the deformation monitoring of the foundation pit,the influence of the construction of the deep foundation pit on the adjacent subway line is clarified.On this basis,the foundation pit slope support schemes are compared and selected,and then the support pile construction,earthwork excavation,main pile foundation construction and earthwork backfilling process control are carried out in turn.The results obtained can provide reference for similar projects.
