【提要】 地鐵隧道附近的施工活動(dòng)，會影響到隧道的正常使用和結(jié)構(gòu)安全。討論了北京緊鄰地鐵隧道某大廈基礎(chǔ)的選型及其對地鐵隧道的影響，針對三種基礎(chǔ)方案，進(jìn)行了平面和三維有限元分析，并對工程的基礎(chǔ)形式提出了經(jīng)濟(jì)、合理、實(shí)用的建議。分析工作對地鐵附近的工程建設(shè)有參考價(jià)值。
【關(guān)鍵詞】 地鐵隧道 有限元 筏板基礎(chǔ) 樁基礎(chǔ)
FEM Analysis for Building Foundation Schemes Adjacent to Metro Tunnels/Guo Hongxian, Wu Qing, Song Shushuang, Jiang Bo(Tsinghua University, Beijing 100084, China)
Abstract:Construction activities adjacent to metro tunnels will affect the use of metro tunnels and the safety of structures. The foundation schemes of a building adjacent to metro tunnels in Beijing are discussed. Three foundation projects are analyzed with 2D and 3D finite element models. Some economical and reasonable proposals are put forward. The research work has reference value to the construction near metro tunnels.
Keywords:metro tunnels； FEM； raft foundation； pile foundation
