Abstract
Permeability is a dominant factor affecting the suction distribution in unsaturated residual soil. However, determination of mass permeability of the residual soil is not a simple matter due to the process involved in the soil formation and the influence of geological structures. Weathering in parent rocks tends to form zones of material with different hydraulic conductivities. These heterogeneities significantly affect water movement in soils by creating a non-uniform velocity flow which is often referred to as preferential flow. Previous publications have highlighted the difficulties in generalizing the hydraulic properties of residual soils. This paper presents a laboratory method developed based on constant head test to determine the mass permeability of residual soil. Results show that the mass permeability of soil increases as the number of relict increases. In addition, comparison with field test data shows that the model gives a good prediction of mass permeability of the soil. Keywords: saturated permeability, relict joint, residual soil, laboratory model
