| Abstract: | Cross-river tunnel and freeze body and adjacent soil finite element models were set up. Through numerical simulation, stress and deformation of the passway frozen soil body of cross passages freezing through the crossriver tunnel were studied. It offers quantitative basis for design of freeze wall, control the freeze impact on surrounding environment and segment lining, etc. It firmly validates the reliability of the construction scheme. The variation of temperature, stress and displacement fields in frozen soil are surveyed on-the-spot during freezing period. According to the result of site-survey, the variation law of stress, displacement in frozen soil were analyzed under dynamic state of temperature field. |
