Swedish Circle Method Swedish circle method for analyzing the slope stability: This method was first introduced by Fellenius (1926) for the analysis of slope stability of C-φ soil. In this method, the soil mass above the assumed slip circle is divided into a number of vertical slices of equal width. The forces between the slices … Continue reading Swedish Circle Method For Analyzing The Slope Stability # 9 Assumptions of Coulomb’s Wedge Theory

# Typical Values of Permeability for Different Soils

Typical Values of Permeability for Different Soils The permeability or coefficient of permeability can be defined as the rate of flow of water through a unit cross-sectional area of the soil under a unit hydraulic gradient at a temperature of C. Typical values of permeability or coefficient of permeability for different soils are as follows: … Continue reading Typical Values of Permeability for Different Soils
