Comparison of Theoretical and Laboratory Permeability for Coarse-Grained Soil at Different Ground Conditions
The permeability of soil plays an important role in estimating the quantity of seepage under foundation of hydraulic structures which in turn affect the stability of structures. Empirical correlations such as Hazen, Kozeny-Carman, Breyer, Slitcher, Terzaghi, USBR, Alyamani and Sen are function of grain sizes, porosity/void ratio, co-efficient of uniformity (Cu), co-efficient of curvature (Cc) and viscosity of pore fluids, etc. These correlations are quite effective for preliminary assessment of permeability during prefeasibility stage. However, at the designing stage, actual measurement of permeability is very important for structural integrity. Soil is not homogeneous, and permeability varies from location to location. Actual ground conditions vary from place to place. Moreover, soil profile is not uniform but varies from one section to other. In some places, it may be dense, partially dense and loose or submerged in water. Depending upon the condition of ground, permeability will also vary from place to place. Keeping in mind the various ground conditions, attempt has been made to determine the co-efficient of permeability on the soil samples remoulded at different compactness and moisture conditions. In the present study, attempt has been made to correlate permeability values obtained through different correlations with laboratories values.
