List 4 functions of why pile foundation is used.
A.
Types of piles refer here.
Pile Foundation Functions
Piles are used if the bearing capacity of soil at shallow depth is not enough to withstand the structural load. So the piles are driven to transfer the loads from the structure to the high bearing capacity soil/rock stratum.
The main functions of using pile foundations are listed below in short.
- To transfer the load from the structure to the foundation at a greater depth where the bearing capacity of soil is efficient to withhold the structure loads.
- Pile controls the soil settlement which can be accompanied by surface foundations.
- Piles are used to increase the safety factor for high loaded structures.
- Piles enable the scope of construction in very low bearing capacity soils.
