What is Pile Foundation? - Civil Engineering
Friction pile transfers the load from the structure to the soil by the frictional force between the surface of the pile and the soil surrounding the pile such as stiff clay, sandy soil, etc. Friction can be developed for the entire length of the pile or a definite length of the pile, depending on the strata of the soil.In friction pile, generally, the entire surface of the pile works to ...
