在地铁隧道建设中,联络通道的位置一般处于各段区间隧道的中间段,在实际工程中,常将其与地下泵站的建设相结合,采用合并建设的模式。主体隧道一般采取矿山法或盾构法进行施工,联络通道的建设通常在主体隧道建设完成后进行,在施工过程中不可避免地要对主体隧道和周围的环境产生影响,直接关系到主体隧道的施工质量,所以其施工方法显得十分重要。 地面土体加固与暗挖法在上海地铁2号线浦东段和浦西段的非闹市区的联络通道施工中采用 In the subway tunnel construction, the location of the liaison channel is usually in the middle section of the tunnels in various sections. In practical projects, it is often combined with the construction of underground pumping stations and the mode of merger and construction is adopted. The main tunnel generally adopts the mining method or the shield method for construction. The construction of the communication channel is usually carried out after the main tunnel construction is completed. In the construction process, it is inevitable to affect the main tunnel and the surrounding environment, which is directly related to the main tunnel Construction quality, so the construction method is very important. Ground reinforcement and undercutting method used in Shanghai Metro Line 2 Pudong section and Puxi section of the non-downtown Liaison channel construction
