| Abstract: | The twin tunnels through Shanghai Huangpu River have a pump room respectively. Freezing method is adopted as the retaining structure for soil excavating in pump room. In order to ensure the safety of construction of pump room, the 3D difference code: FLAC3D is employed for simulating the process of soil excavation in pump rooms. Considering the excavation steps, the mechanical mechanism of frozen wall is studied. Finally, the measures assuring the safety of construction are also investigated, and the reasonable advice guiding the construction is proposed. |
