摘　　要：为研究复杂环境下北京地铁十四号线平乐园站~九龙山站区间暗挖三联拱隧道地表沉降控制,采用有限元软件Plaxis进行了三联拱隧道施工工序数值模拟,通过定性分析,明确了各施工工序的沉降值,给出了开挖的分步最大沉降值及总沉降量,并与实测结果进行对比,吻合较好,可为其他类似工程提供参考。In order to study the three arch tunnel of Pingleyuan station-Jiulongshan station tunnel on No.14 line of Beijing metro subsidence control in complicated condition,simulation of the three arch tunnel construction process with the finite element sofiware,through qualitative analysis, defined the settlement value of the construction process, and gives the excavation step the maximum settlement value and the total set- tlement value,and compared with the actual measurements,the results were well. The research can provide a reference for other similar projects.
