In soft clay of low bearing capacity, the type of steel pile generally used, is A. H-pile B. Screw pile C. Disc pile D. Pipe pile

Disc piles are steel piles that have a disc on the end. The disc is used to create a bearing surface on the ground. Disc piles are often used in soft soils because they can be driven into the ground without compacting the soil.

Pipe piles are steel pipes that are driven into the ground. They are often used in waterlogged soils because they can be driven into the ground without displacing the water.

In soft clay of low bearing capacity, H-piles are generally used because they are strong and can be driven into the ground without compacting the soil.
