Upload NowIn the theory of compression, soil compression is assumed to occur by the decrease in the volume of voids, the volume of solids remaining constant throughout the process. Also, higher the effective stress in soils, higher is the resulting compression. Hence, the compressibility of soils is expressed in the terms of a plot between void […]

Three-Dimensional Consolidation of Soil | Soil Engineering
Article shared by :
Terzaghi’s theory of consolidation assumes that the expulsion of pore water during consolidation takes place in vertical direction alone. This is generally true for most of the cases, where the pervious layers, which form the drainage faces, are horizontal, located above and /or below the compressible soil layer. In some special cases, where vertical sand […]
How to Determine the Permeability of Aquifers? | Soil Engineering
Article shared by :
The various types of in situ tests commonly used to determine the permeability of aquifers in the field are: 1. Pumping-out test. 2. Pumping-in Test. Compared with laboratory methods, field methods give a more reliable value of permeability, since the soil is tested in situ without disturbing its structure and void ratio. The value of […]
