| Abstract: | Frozen method is widely used in the connected aisle of metro. It is important to guarantee the safety of the connected aisle through the design temperature and thickness of frozen wall. In order to illustrate the mechanical behavior and grasp the influence of soil excavated inside the connected aisle on the frozen wall, 3-D numerical simulation of the process of the frozen construction is employed by the code for Flac3D. Considering the impact of excavation steps on the frozen wall, some valuable results which are available for other engineering, are obtained. |
| Keywords: | metro connected aisle frozen method numerical simulation in three dimensions |
