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.
