A 500 mm diameter and 25 m long driven concrete pile carries a column load of 1600 kN. It is estimated that the shaft carries 1200 kN and the point carries 400 kN. Determine the settlement of the pile head with the following data: Elastic modulus of soil, Es = 18 MPa; Elastic modulus of pile, Ep = 32,000 MPa; Poisson's ratio of the soil, Hs = 0.2; Layer thickness, H, is very deep (assume H = ∞). %3D

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.
