Why is Soil Important? What is the Bearing Capacity of Soil?
Soil is a thin layer of material covering the earth's surface and is established by the weathering of rocks. Solis plays an essential part while pouring footings; the soil's load-bearing capacity must be checked before using the soil's surface.
Building foundations need to be on a stable and robust soil. Different soils have different ranges in strength. Some soils are strong enough to build a high-rise building, while others can not even handle the weight of a single human. If the soil under a piece of construction is unstable, the building's foundation could sink crack, and for the worse, the entire structure could collapse.
To check the stability, strength, and capacity of the soil there, different properties have to be measured. One such property which is very important to measure is the bearing capacity of the soil.
The soil bearing capacity is referred to as the magnitude of soil to withstand any external load applied to it. In layman's terms, it is defined as the capacity of the soil to support an amount of load and pressure without failure.
The bearing capacity of soil can be distinguished into two parts:

1.?Allowable bearing capacity?is the maximum amount of pressure that can be applied to the soil from its foundation.
2.?Ultimate bearing capacity: The minimum pressure will cause the supporting soil to collapse instantly below and close to the foundation.
The maximum load per unit area that the rock or soil could carry without breaking up or without any displacement is termed as the bearing capacity of soils.
The properties of soil, such as density, strength, and permeability, all affect the bearing capacity of the soil. In addition, soils resistance to deform depends upon factors like bulk density, water content, angle of internal friction, and the process in which load is being applied to the soil.
