Friction piles, also known as floating piles, are essential in deep foundation construction, providing stability for large structures like bridges, roads, and stadiums. These piles rely on frictional resistance between the pile surface and surrounding soil to transfer the superstructure’s load, ensuring a strong and steady foundation where topsoil alone cannot support the weight.
Friction piles are particularly useful in areas where excessive soil settlement is a concern or where deeper, more complex soil layers make traditional pile foundations uneconomical. These piles generate bearing capacity through shear stresses along their sides, efficiently distributing loads through skin friction. Commonly made from steel or reinforced concrete, friction piles are long, slender elements extending at least three times the width of the structure into the ground.
To determine the capacity of a friction pile, multiply its surface area by the safe friction force per unit area. Enhancing capacity involves increasing pile diameter, depth, number, and surface roughness. Steel pipe piles are particularly effective due to their large surface area, offering superior frictional load resistance. Steel-concrete composite piles further enhance durability and driveability, while H-piles and wide flange beams are commonly used due to their strength and uniform thickness.
