Concept explainers

Pricing Excavation and Backfill

Backfill, in construction, is the activity of returning the soil and gravel that are removed during building construction or using them again to toughen and support the foundation of the building or any other structural component.

Question

As driven piles penetrate into a saturated clay soil, why the material in the vicinity of the pile is remolded?

Expert Solution

Step 1

Once a pile is driven into clay, the soil around the pile develops vertical and horizontal movements.

Step 2

Such movements would continue to develop axial forces and bending moments in already installed adjacent piles.
