Question

Friction piles are most effective in which type of soil

Answer 1

Answer:

Friction (or floating) piles develop most of the pile-bearing capacity by shear stresses along the sides of the pile, and are suitable where harder layers are too deep to reach economically. The pile transmits the load to surrounding soil by adhesion or friction between the surface of the pile and soil, which in effect lowers the bulb of pressure. In other words, the whole surface of the pile (cylindrical in shape) works to transfer the forces to the soil.

Answer 2

They are effective in clayey soils.

• These considerable piles are beneficial when the strong strata are very deep and end-bearing piles are becoming economically prohibitive.
• These piles can additionally successfully serve the specific function in such instances by naturally resisting the operating weight via skin friction.
• When clayey soils are naturally found, these piles are generally considered more effective.
• This is due to the higher adhesion coefficient of clayey soils.
