山地城市超大断面暗挖地铁车站初支拱盖法施工技术
Research on Initial Support Arch Cover Method Construction Technology for Large-span Underground Metro Stations in Mountainous Cities
摘要
Abstract
Taking the Daping West Station of Chongqing Subway as the engineering background,this paper analyzes the key and difficult issues in the construction of subway stations in the core areas of mountainous cities.It introduces the construction procedures of the initial support arch cover method and elaborates on the key construction technologies of this method,including excavation and muck removal of the tunnel body,initial support of the station main body,removal of temporary support,and backfill grouting behind the initial support.Engineering practice has shown that this technology is suitable for the construction of large-section dark excavation subway stations in mountainous cities,and it can improve the safety and economy of construction.The research results can provide reference for similar projects at home and abroad.关键词
