Mechanical Bevahiour of an Unsaturated Soil Associated with Seepage
Frequently, residual soils form under unsaturated conditions because of volatile fluids with different absorption coefficients at the chemical interface between the skeleton and fluid. That leads to the large requirement of controlling the stress increment derived from suction potentials by performing constant shear tests to water, leachate and gasoline infiltrations. Thus, the saturation with fluids having different specific weights and viscosities than water may occur in the unsaturated gaseous zone, adsorbed according to their physical and chemical properties (volatility, solubility, adsorption coefficient) as well as the time that has gone after contamination. Analysing these phenomena is of particular interest to evaluate the mechanical parameters and changes in shear strength.
