上海地铁"十"形换乘地铁车站施工技术

上海轨道交通9号线西藏南路站和8号线陆家浜车站是典型的"十字"换乘段车站,9号线西藏南路站在施工过程中遇到了地面建筑密集、交通设施繁忙、地下管线众多、地下水位高等难题。该文阐述了典型"十"形换乘地铁车站施工技术,很好地解决了基坑在开挖过程中存在的诸多困难。使用该技术施工,有效地控制了基坑的变形,确保了交通干道的畅通及周边建筑物的安全。

Construction Technique of Shanghai Metro "Cross-shape" Interchange Station

Shanghai Metro No.9 Line Xizang Road (S) Station and No.8 Line Lujiabang Road Station are the typical "cross-shape" interchange stations. The difficulties of the dense ground buildings,heavy traffic facilities,many underground pipelines and high underground water level occurred in the construction of No.9 Line Xizang Road (S) Station. The article sets forth the typical "cross-shape" interchange metro station construction technique,and better resolves many difficulties existing in the excavation of the foundation pit. This technical construction is used effectively to control the deformation of the pit and ensure the smoothness of the trunk traffic and the safety of the surrounding buildings.
