The silty clay soil is a type of soil which is not capable of supporting a structure, deep foundations are required to transfer the loads. The most common types of deep foundations are Piles, Piers and Caissons.
By using the soil properties such as Liquid limit, Saturated density, Optimum moisture content etc,. The pile foundation can be designed.
A pile is a slender structural member made of steel, concrete or wood, which is either driven into the soil or formed in-situ by excavating a hole and filling it with concrete.
Application of pile foundation:
If the plan of the structure is irregular relative to its outline and load distribution, it can be used to reduce differential settlement.
It can resist horizontal forces in addition to support vertical loads for earthquake prone areas & tall buildings.
Piles are used for foundations of some structures such as, transmission towers, off-shore platforms which are subjected to uplift.
Piles are used to transfer the load beyond the zone of possible moisture changes in collapsible soils.
