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, ...
Important Shrinkage Parameters in Soil Engineering
The important parameters related to shrinkage limit in soil engineering are shrinkage index, shrinkage limit, volumetric shrinkage, and linear shrinkage. Each parameter is briefly explained in this article. 1. Shrinkage Index ( Is ) The numerical difference between the liquid ...
What is Soil Suction?
Soil suction is defined as the state of the soil when it is under reduced pressure. It is measured in terms of the height of the water column (h) suspended in the soil. The main features and factors affecting soil ...
How to Measure Soil Suction?
The suction in soil mass can be measured mainly by three methods namely Tensiometer method, Suction Plate method and Centrifuge Method. Each method is briefly explained below. 1. Tensiometer Method The figure-1 below shows the arrangement of tensiometer to determine ...
Determination of Water Content by Sand Bath Method
Sand bath method is a field method conducted to determine the water content of the soil. This method is fast but the result is not as accurate as the oven-dry method. Also Read: Determination of water content by oven dry ...
5 Basic Volumetric Relationships in Soil Engineering
The five important volumetric relationships used in soil engineering are void ratio, porosity, percentage air voids, degree of saturation and air content. Each relation is mentioned and explained briefly in this article. 1. Void Ratio Void ratio(e) is defined as ...
Determination of Water Content in Soil By Torsion Balance Method
Torsion balance method is one of the methods that determine the water content of the soil rapidly. The method employs an infrared lamp and torsion balance to determine the moisture content rapidly and with high accuracy. The test apparatus and ...
