What Is the Difference Between Shallow Foundations and Deep Foundations

Question

Examlex · Accepted Answer

The Answer is Shallow foundations and deep foundations are two types of structural support systems used in construction. The main difference between the two lies in their depth and the load-bearing capacity they provide.

Shallow foundations, also known as spread footings, are typically used when the soil near the surface has sufficient bearing capacity to support the structure. These foundations are placed close to the ground level and transfer the building loads directly to the soil. Shallow foundations are commonly used for smaller buildings, residential homes, and structures with light loads.

On the other hand, deep foundations are used when the soil near the surface is not strong enough to support the structure, or when the building loads are too heavy for shallow foundations to bear. Deep foundations are installed deep into the ground, reaching stronger, more stable soil layers or bedrock to provide the necessary support. Examples of deep foundations include piles, drilled shafts, and caissons. Deep foundations are recommended for tall buildings, bridges, large industrial structures, and in areas with poor soil conditions.

In summary, the choice between shallow and deep foundations depends on the soil conditions, the size and weight of the structure, and the specific requirements of the construction project. Deep foundations are recommended when the soil near the surface is weak or when the building loads are heavy, making them necessary for ensuring the stability and safety of the structure.
