城市地下空间开发与轨道交通施工新技术

针对上海地区地下空间开发、轨道交通网络化发展以及城市密集区域工程建设的发展需求,对多线换乘地铁枢纽站改扩建、深层地基加固、地下深层障碍物清除、盖板逆筑、既有地下空间利用加层等多项施工新技术进行了研究和开发,并通过实际工程应用证实了各项技术的有效性,可为今后城市密集地区和复杂建设环境下的地下空间开发和施工建设提供借鉴。

Urban Underground Space Development and Rail Transit New Construction Technology

To meet the demands of Shanghai underground space development,rail transit network development and engineering construction in dense urban area,several new construction technologies are developed including the re-building and expansion of multi-line interchange station,deep foundation consolidation,clearing away deep underground obstructions,top-down construction method,using existing underground space and adding layers.These technologies have been proven to be valid through practical engineering applications and can be used in the underground space development and construction in urban areas and complicated engineering environment in the future.
