Upload NowAs the consolidation settlement depends on both the initial and final stress levels and because there is significant difference in consolidation settlement due to virgin compression and re-compression, stress history has a significant effect on compression of clays. Influence of Stress Cycle: The relation between soil compression and effective stress is not unique even for […]

Three-Dimensional Consolidation of Soil | Soil Engineering

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 […]
