Darcy’s law states that the discharge or rate of flow per unit time is proportional to hydraulic gradient. Generally the laminar flow velocity through homogeneous soil is represented by Darcy’s law. It is represented by a simple equation as, V ∝ i OR V = Ki ……(eqn … Read more
When the water flows in the upward direction from water table to capillary fringe, it generally gets freeze when the temperature falls below freezing point and this term is referred as ‘frost heave or frost heaving‘. In simple terms frost heaving means the contraction and expansion of soil due to freezing and thawing conditions. Due … Read more
Three Phase System of Soil is nothing but the soil mass made up of solid, liquid and gaseous matter. The solid particles present are called as soil grains. The free space or void present between the solid particles is generally filled partially with water and air. Here liquid phase is generally referred as to water … Read more
The soil structure can be defined as the proper geometrical arrangement of particles of soil with respect to each other. Structure of Soil is one of the major factor which impacts many different properties of soil such as compressibility, permeability and shear strength of soil etc. Mainly there are five types of soil structures which … Read more
The origin of the soil is nothing but the mechanical disintegration and chemical decomposition of rocks. Generally when big rocks gets exposed to atmosphere, with time they get disintegrated and decomposes forming natural soil. Basically on the formation of the soil, it can be grouped into 2 categories namely : Residual Soil and Transported Soil. … Read more
What is Soil Stabilization Definition : The engineering properties of poor soils can be improved by the use of admixtures is known as soil stabilization. In simple terms, the engineering properties of soil are modified to attain the more stable soil. The stabilized soil may form the sub-grade or wearing layer of road. Necessity of … Read more
CBR Test of Soil 【Definition】 The california bearing ratio test (CBR test) is defined as the ratio of the test load to the standard load, expressed as percentage for a given penetration of the plunger. Theory of California Bearing Ratio ( CBR ) Test Procedure In this method the combination of load penetration test performed … Read more
What is Caisson Foundation ? A Caisson Foundation is a watertight retaining structure used as bridge pier in the construction of concrete dam, or for the repair of ships. Caisson Foundation is also known as Well foundation. They are build in such a way that the workspace is always kept dry by pumping out the … Read more
Particle Size Distribution Particle Size Distribution or the percentage of grains of different sizes in a given soil is an important property of soil. Particle size analysis of coarse soils is carried out by sieve analysis or mechanical analysis whereas fine-grained soils are analysed by hydrometer analysis. In general, a combined analysis is carried out … Read more
Bearing Capacity of Soil The soil is generally used as a substratum on which the the foundation of the structure and hence the structure too rests. The soil below the foundation should be strong enough to withstand the load of the entire structure. The load of foundation is compressive, but shear force also enacts doe … Read more
