“零距离”穿越运营地铁车站的综合施工技术

受原先规划制约,上海地铁1号线未为后期的其它线路留设接口,给其它线路与地铁1号线的换乘施工带来了较大难度.结合上海地铁4号线上体场车站工程,介绍了桩基托换、人工地层控制冻结、加固保护等综合技术措施在工程中的应用,使地铁4号线成功穿越地铁1号线上海体育馆车站,这对其它类似工程的施工具有一定的借鉴意义.

Comprehensive Construction Technology of Passing Through Running Metro Station in Zero-Distance

Restricted by former plan,Shanghai metro line No.1 was not left a j un ction with future other lines ,this results in quite difficulty in construction of transfer between other lines and No.1 line .Combined with Shanghai Gym Statio n of Shanghai No.4 metro Station Project,some comprehensive technigues and measu res such as pile replacement,artifical ground freeging reinforcement and protect ion applied for this project etc are introduced.The No.4 line is made to success fully pass through Shanghai Gym Stotion of the No.1 Line.It gives some other sim ilar projects for a certain reference.
