南京地铁2号线上新区间施工关键技术研究

Technologies Used in Shang-Xin Section Construction for Nanjing Metro Line 2

针对南京地铁2号线上海路站—新街口站区间隧道所遇到的避免管线改迁、小间距群洞室、软流塑、富水等关键技术进行研究,并采取了一系列的工程措施,确保了该区间隧道的施工安全,取得了很好的技术与社会效应。

In order to avoid the pipeline resettlement encountered in the tunnel construction for section between Shanghai Road Station Xinjiekou Station of Nanjing Metro Line 2,difficulties of small spacing group of chambers,soft plastic flow,and water-rich problems,the key technologies are studied.A series of engineering measures are adopted to ensure the safety of the section tunnel construction,very good technical and social effects are obtained.
