摘要
目前,在城市地下快速路施工过程中,穿越既有轨道交通隧道的情况越来越多。结合杭州某地下快速路通道工程,基于大直径泥水平衡盾构下穿隧道的监测数据,研究大直径泥水平衡盾构下穿过程中的隧道变形特性。以此为依据,建立三维有限元模型,研究轨道交通隧道变形与下穿隧道上浮量的关系,从而提出相关的变形控制施工措施,给类似工程施工提供参考。
At present, more and more urban underground expressways have to undercross the existing rail transit interval tunnels. Combined with the construction of an underground expressway in Hangzhou, the deformation of rail transit tunnel is studied based on the monitoring data of the large diameter slurry shield undercrossing the rail transit tunnel. A three-dimensional finite element model is established to study the relationship between the deformation of rail transit tunnel and the buoyancy of undercrossing tunnel. Relevant construction measures to control tunnel deformation are provided which can be referred for similar projects.
