CE 240 Soil Mechanics & Foundations Lecture 4.3 Permeability I (Das, Ch. 6) Outline of this Lecture 1. Permeability in Soils 2. Bernoulli’s Equation 3. Darcy’s Law 4. Hydraulic Conductivity 5. Hydraulic Conductivity Tests Due to the existence of the inter-connected voids, soils are permeable. The permeable soils will allow water flow from points of high energy to points of low energy. Permeability is the parameter to characterize the ability of soil to transport water. Permeability in Soils • Permeability is the measure of the soil’s ability to permit water to flow through its pores or voids • It is one of the most important soil properties of interest to geotechnical engineers Soil Permeability Soil Properties Physical (Soil Characteristics) Mechanical Specific Gravity Moisture Content Unit Weight Gradation Atterberg Limits Compaction Permeability Compressibility Strength (Shear) 1 – Constant-Head Test 2 – Falling-Head Test Importance of permeability ..
