An Analysis of the Influence of the Temperature on the Capillary Migration of the Residual Soil

Abstract:

Taking the granite residual soil of Fujian Province as an example, this paper investigated the humidity migration law of the granite residual soil pillar embankment under the co-influence of temperature and capillary based on the finite difference technology. The results show that the temperature and humidity of the surface of the soil pillar take on the linear downward trend under different temperature gradients, and the larger the temperature gradient is, the wider the falling range will be. The temperature and humidity migration volume of the hot end of the soil pillar presents the linear variation along with the increase of the average temperature. The change of the temperature field of the residual soil pillar is mainly influenced by the temperature gradient. The humidity migration volume and the rising height of the capillary water are obviously more strongly influenced by the average temperature than the temperature gradient. Therefore, it is necessary to study the influence of the temperature-humidity coupling on humidity migration for the low embankment of the high underground water level in the hot-humid area.
