摘　　要：以深圳地铁9号线鹿丹村站后渡线隧道为例,采用数值模拟的分析方法,对大跨度地铁渡线隧道施工过程进行数值模拟,分析E断面分别采用双侧壁导坑法和CRD法施工对衬砌内力和变形的影响,并对CRD法开挖顺序进行探讨,对隧道的施工方法和开挖顺序提出优化建议。Taking the tunnel in transmission line after Ludancun Station of Metro Line 9 in Shenzhen for example,the numerical simulation analysis method is adopted to perform numerical simulation of tunnel construction process of big span metro transmission line. For section E,the double side drift method and CRD method are adopted to analyze the internal force of lining and influence of deformation; the excavation sequence by CRD method is discussed and optimization suggestions for tunnel construction methods and excavation sequences are put forward.

关 键 词：地铁隧道 双侧壁导坑法 CRD法 数值模拟 方法优化
