| Abstract: | Taking the special engineering properties of frozen soil subgrade into account, that the effects for results of moisture migration , which is meant the variation of water content, on the temperature field especially on the heat physical parameters are studied. Meanwhile, the effects for variation of temperature on the moisture migration mechanism of soil and its calculting method are studied too. Hence, the calculation model for the coupled temperature and moisture migration of the frozen soil subgrade is put forward, and the general flow - chart for calculation scheme of coupled temperature and moisture imgration is given. Based on the calculation results from an example, which the transverse difference for the temperature field and water content state of frozen soil subgrade has been revealed. |
