Seepage velocity and Seepage pressure

The velocity of water obtained using the total cross-sectional area of the soil is known as discharge velocity or superficial velocity. Since water flows only through voids and not through the total cross-sectional area, the actual velocity of water is much higher than the discharge velocity and that is known...

Various causes of Dampness in building

Causes of Dampness are: (i) Rising of Moisture from the Ground: The sub-soil or ground on which the building is constructed may be made of soil which easily give an access to water to create dampness in building through the foundation. This Moisture may rise up into the wall and...

How Earthquake Resistant buildings are Planned?

The earthquake resistant buildings are planned in the following ways: (i) Symmetry: The building as a whole or its individual blocks should be kept symmetrical about both axes. Asymmetry leads to torsion during earthquakes and is very dangerous; symmetry is also desirable in the arrangement and size of door and...

Causes of Water logging

Causes of Water logging are: (i) Seepage of water through canals: Seepage of water through the bed and sides of adjacent canals, reservoirs, etc., which are higher than the affected land, results in a high water table. If the soil at the site of canals, reservoirs, etc. is highly permeable,...

Void Ratio, Porosity, Degree of Saturation

# Void ratio describes the relation between the free space between loose particles. # Porosity describes the void directly at the surface of a particle. Void ratio Voids ratio (e) of a given soil sample is the ratio of the volume of voids to the volume of soil solids in...

Three phase diagrams in Geotechnical engineering

Soil is defined as a three-phase system consisting of solid, water and air which are intermixed with each other and whose relative proportion decides the property of soil. Three Phase Diagram of Soil Here, W = total weight of soil massWa = weight of airWw = weight of waterWs =...
