BASIC KNOWLEDGE ABOUT PILE FOUNDATION, HOW TO CALCULATE QUANTITY FOR PILE FOUNDATION BY CIVIL GURUJI
Foundations provide support to the structure, transfers the loads from the structure to the soil. But the layer at which the foundation transfers the load shall have an adequate bearing capacity and suitable settlement characteristics. There are several types of foundation depending on various considerations such as-
Total load from the superstructure.
Soil conditions.
Water level.
Noise and vibrations sensitivity.
Available resources.
Time-frame of the project.
Cost.
Broadly speaking, foundations can be classified as shallow foundations and deep foundations. Shallow footings are usually used when the bearing capacity of the surface soil is adequate to carry the loads imposed by a structure. On the other hand, deep foundations are usually used when the bearing capacity of the surface soil is not sufficient to carry the loads imposed by a structure. So, the loads have to be transferred to a deeper level where the soil layer has a higher bearing capacity.
What is Pile Foundation?
Pile foundation, a kind of deep foundation, is actually a slender column or long cylinder made of materials such as concrete or steel which are used to support the structure and transfer the load at desired depth either by end bearing or skin friction.
Pile foundations are deep foundations. They are formed by long, slender, columnar elements typically made from steel or reinforced concrete, or sometimes timber. A foundation is described as 'piled' when its depth is more than three times its breadth.
Pile foundations are usually used for large structures and in situations where the soil at shallow depth is not suitable to resist excessive settlement, resist uplift, etc.
Following are the situations when using a pile foundation system can be
When the groundwater table is high.
Heavy and un-uniform loads from superstructure are imposed.
Other types of foundations are costlier or not feasible.
When the soil at shallow depth is compressible.
When there is the possibility of scouring, due to its location near the river bed or seashore, etc.
When there is a canal or deep drainage systems near the structure.
When soil excavation is not possible up to the desired depth due to poor soil condition.
When it becomes impossible to keep the foundation trenches dry by pumping or by any other measure due to heavy inflow of seepage.
