Dynamic Cone Penetrometer, or DCP, is a tool used for evaluating the strength of soils on site. It also helps with monitoring the condition of granular layers and subgrade soils in pavement sections over time. It can be used to ...

Determination of Maximum Dry Density and Optimum Moisture Content of Soil -IS:2720 (Part VII)
Relationship between maximum dry density of the soil and the water content can be obtained by soil compaction test. This relationship helps in determining the optimum water content at which maximum dry density of soil can be attained through compaction.
Determination of In-situ Density of Soil by Water Replacement Method
The water replacement test method is used for the determination of field density of soil and rocks (includes materials that commonly contain particles larger than 75mm) in a test pit based on the ASTM D5030. It is specifically used for ...
What is Uplift Pressure? Effects on Foundations, and Prevention Strategies
Uplift pressure, which is also known as hydrostatic uplift, is an upward pressure applied to a structure that has the potential to raise it relative to its surroundings. It is the condition of greater pore water pressure than the overburden pressure ...
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 ...
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 ...
Factor of Safety for Bearing Capacity of Soils
Factors of safety for bearing capacity is a value which is established based on the type of soil, method of exploration, level of uncertainty in soil, importance of structure and consequences of failure, and likelihood of design load occurrence. So, ...
