What is soil mechanism and why it is important to study properly
Many students want to do Civil Engineering due to its scope in their careers. Passionate students join this engineering program as it is quite interesting. But while studying, there are a lot of papers in which students face difficulty. Soil Mechanism is one of them.
So let’s discuss this:
About soil mechanism
Soil mechanism is an important sub-branch of civil engineering that deals with the study of different properties and behavior of soil. Soil is the basic component that is required in all the major Civil Engineering applications like building, bridges, dams, embankment, retaining walls, and pavements. At different places, the behavior and properties of soil differ from each other. They also differ in depth and cannot be ascertained and controlled like that of Steel and concrete. So, it becomes important to investigate and study the different prope
rties of soil to bring actual results to the applications. In ca, if the soil is not able to support the structures, then the properties of the soil need to be improved and that comes underground improvement process.
Nowadays, the Other important applications of soil mechanics are to remediate and enhance ground properties, which are contaminated by some source of pollution. However, this is termed geoenvironmental engineering.
There are mainly two groups of soil.
Cour grained soil
This type of soil is formed by physical weathering.
Fine-grained soil.
This type of soil is formed by chemical weathering.
Majorly, the properties of soil are divided into two heads – index properties and Engineeri
ng properties.
Index properties
The properties of tho that are helpful in the classification and identification of the soil for Engineering applications. Overall, soil compris three phas – solid particles, water, and air. Besides, some important index properties for different types of soil are as follows-
Coar-grained soil
1- particle size distribution 2- particle shape 3- relative density
Fined grained soil
1- consistency 2- clay and clay mineral content 3- plasticity characteristics
Engineering properties
Engineering properties of soil characteristics are tho that are obrvable, measurable,
and that influences the behavior to the extent that is esntial in engineering analysis and design. The engineering properties are –
Permeability
It is known as the ca through which water can flow through the soil under the hydraulic gradient.
Consolidation
It is the time-dependent process that results in volume change. However, it appears becau of squeezing out of per water under steady loading.
Compaction
It is mechanically improving the density of unsaturated soil by reducing the volume of air in voids. Subquently, compaction is different from consolidation.
