A Mathematical Model for Subgrade Soil Water-Vapor Migration

Abstract:

In arid and semi-arid areas, water vapor transfer in non-saturated soil is usually more significant. Based on the existing theories such as soil mechanics and fluid mechanic, as well as the features on water vapor transfer in non-saturated soil, a formula to calculate the saturated water vapor pressure in soil void by taking the matrix suction and temperature into account was got, and a mathematical model for the moisture migration with time was deduced which reveals that a water-vapor migration phenomenon is uneven temperature distribution and uneven distribution moisture alone or in combination manifestations.
