Laboratory tests

• The permeability coefficient is the product of hydraulic conductivity (K) and saturated thickness (H).
• Infiltration rate is the amount of water that enters the ground surface per unit time, measured as depth/time.
• Permeability refers to the ability of soil or rock material to transmit fluids.
• Porosity is the ratio of void space to total volume of soil.
• Permeameter test measures the flow of water through soil samples under controlled conditions to determine their permeability.
• Infiltration rate is the amount of water that can be absorbed by the ground surface over time, measured as depth/time.
• Porosity is the ratio between void space and total volume of soil.
• Saturated hydraulic conductivity is the maximum rate at which water can move through an unsaturated porous medium when it is fully saturated with water.
• Consolidometer test determines the compressibility characteristics of soils by measuring changes in volume with increasing pressure.
• Unsaturated hydraulic conductivity is the rate at which water moves through an unsaturated porous medium under given conditions.
• Triaxial shear strength test evaluates the mechanical properties of soils subjected to different stresses and strains.
• Saturated hydraulic conductivity is the maximum rate at which water can move through a porous medium when all pore spaces are filled with water.
• Unsaturated hydraulic conductivity is the rate at which water moves through an unsaturated soil under a given set of conditions.
• Soil compaction is the process of increasing the density of soil particles by applying pressure.
• Triaxial shear strength test evaluates the mechanical properties of soil specimens subjected to different stresses and strains.
• Soil compaction involves applying pressure to compact soil particles together, reducing air spaces between them.
• Direct shear box test assesses the frictional resistance between two surfaces sliding against each other.
• Compacted soils have higher density and lower porosity compared to loose soils.
• The permeability coefficient (k) is calculated from the slope of the log-log plot of the Darcy equation.
• Density index (DI) is used to measure the degree of compaction achieved during construction activities.
• The permeability coefficient (k) is determined using the Darcy equation.
