摘　　要：随着地铁规模日益增长,施工中会出现各种复杂的工程问题,而现有的工程案例数量较少,对解决特殊地铁车站形式施工尚未形成一套较完善的体系。基于分离岛式车站特殊车站形式,通过对比群洞施工工法优劣势及施工变形影响因素,继而利用实际工程案例监测数据分析归纳总结出施工变形规律,并给出群洞暗挖施工洞内外变形风险控制措施,有利于后续解决相似工程背景下的施工问题。With the increasing scale of subways, various complex engineering problems will appear in construction. However, the number of existing engineering cases is relatively small, and a relatively complete system has not been formed to solve the construction of special subway stations. This paper is based on the special station form of the separated island station, by comparing the advantages and disadvantages of the group tunnel construction method and the influencing factors of construction deformation, and then using actual engineering case monitoring data to analyze and summarize the construction deformation law, and the group risk control measures are given for the deformation of the inside and outside of the tunnel under construction. It is conducive to the subsequent resolution of construction problems in the context of similar projects.
