| Abstract: | This paper studies the variations of the freezing pressure of the freezing walls in the thick clay strata, against the temperature change by the field measured results. Combining the analysis of actual measured data with the numerical model of the ADINA FEM method, the artificial freezing stress field is simulated to provide a reference for the engineering practice. |
