摘　　要：以分析基坑开挖引起紧邻车站变形为切入点,对北京地铁宋家庄枢纽站的后期工程基坑开挖进行数值分析,研究了不同施工方案下既有宋家庄车站结构的变形情况,分析了后期工程实施过程中存在的典型风险源,并提出了相应的工程对策。Taking the analysis on distortion of near station caused by foundation pit excavation as the breakthrough point, the numerical analysis on foundation pit excavation in the later stage of Songjiazhuang Station project of Beijing Metro is carried out. The distortion conditions of the structure of existing Songjiazhuang Station under different construction schemes are investigated. The typical risk sources existing during the later project implementation are analyzed. The corresponding engineering countermeasures are presented.
