摘　　要：日益复杂的地铁建设环境使得地铁线路布置困难,施工风险加大,同时对施工方法和车站型式的选择也提出了更为严格的要求。以北京地铁14号线试验段车站建设为背景,对大直径盾构扩挖修建车站的方案设计和型式进行了分析研究和比选。结果表明,采用大直径盾构扩挖地铁单洞双线区间并在盾构隧道基础上小规模扩挖形成车站是解决复杂环境下地铁建设的一种新思路;从总体的工程量和施工难度上相比,单洞双线侧式车站型式比单洞双线岛式车站型式更有优势;与传统车站型式相比较,经济性还需要根据试验段实施情况进一步研究。The increasingly complicated environment leads to difficult layout of metro lines,increasing construction risks and stricter demands on construction methods of metro engineering and the selection of station type.Taking the trial section project of the Beijing metro Line 14 as subject investigated for the construction schemes,the design schemes and station type of metro station driven with large-diameter shield is analyzed and compared.The results show that a running tunnel with two tracks constructed by large diameter shield machine and mining method to enlarge large diameter shield tunnel can be regarded as a new idea of metro station construction under complex environment.In terms of the general engineering and construction difficulty,the side-platform station of single-line tunnel has advantage over the island-platform station of double-line tunnel.Compared with the traditional station type,the economy also needs further study based on the condition of the trial section project.
