瘦西湖隧道工程采用直径为14.93m超大直径盾构机,盾构施工的施工方法存在施工空间限制、施工场余郁地,几钱乎锋处于封闭状态等的局限。隧道的施工方案、支护参数和力学行为是单管(扬双州层市隧市道政建建设设处研,究江苏的扬重州点,和225难10点0)。结合扬州市瘦西湖隧道工程实例,基于多目标优化理论的同步快速施工技术,很好地解决了单管双层盾构隧道内部结构同步施工技术难题。
Slender West Lake tunnel project uses a diameter of 14.93m large diameter shield machine, shield construction methods exist in the construction space constraints, the construction site Yu Yu, a few Qian Qian front in the closed state and other limitations. The construction scheme, supporting parameters and mechanical behavior of the tunnel are single-tube (Yangzhou Shuangzhou City, the city’s municipal government construction and research office building, research Yangzhong Jiangsu point, and 225 difficult 10:01). Combined with the project of Slender West Lake Tunnel in Yangzhou City, the synchronous rapid construction technology based on multi-objective optimization theory can well solve the technical problems of simultaneous construction of single-tube double-decked shield tunnel.
