Numerical Simulation of Coupled Rainfall and Temperature of Unsaturated Soils

Abstract:

As a kind of porous medium made of grains, water and air, under some transfer influences, the soil in some certain atmosphere circumstances has the transfer of heat, water and air, which leads to people’s interesting. The change of temperature influences engineering, such as soils’ consolidation, expansion, grains’ force and pore pressure and so on. The paper gives a coupled numerical simulation of atmosphere rain, temperature of soils and gives the correlation between rain and temperature in unsaturated soils. The different clock of the rain begin in day little influences seepage field, due to the superficial part the sun influences; otherwise the temperature has an great influence on the permeability coefficient and diffusion coefficient.
