What is the Effective Stress Principle in Soil Engineering?
The effective stress principle in soil engineering is one of the important theories put forward by Karl Terzaghi in the year 1936. It is the difference between total stress and pore water pressure. More features and determination of effective stress ...
What is Bridge Pier? Types of Bridge Piers
A bridge pier is a type of structure that extend to the ground below or into the water. It is used to support bridge superstructure and transfer the loads to the foundation. The bridge piers can be constructed to be ...
What are the Bearing Capacity Values of Different Soils?
The capacity of the soil to allow the loads coming from the foundation is called bearing capacity of the soil. The gross pressure at the base of the foundation at which soil fails is called ultimate bearing capacity. By considering ...
What are the Foundation Design Requirements?
There are many design requirements that foundation structure need to met in order to perform its function adequately and serve its purpose. For instance, it should be strong enough to minimize differential settlement and should be able to safely support ...
Variable Head Permeability Test of Soil- Purpose, and Procedures
Variable head permeability test is one of several techniques by which the permeability of soil is determined. It is used to evaluate the permeability of fairly less previous soil. Permeability is the measure of the ability of soil to allow ...
Permeability of Soil – Features, Darcy’s Law
The property of the soil by which it permits the flow of fluid through it is called permeability of the soil. The porosity in the soil material is contributed by the presence of interstices within it. The property of permeability ...
What is Frost Action in soils and How to prevent it?
The two critical frost actions in the soil are the frost heave and the frost boil. Frost heave is the phenomenon in which the water molecules present in the pores freeze during lower temperature which results in the expansion of ...
