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

Describe about the Relation between pile capacity and driving.

Expert Solution

Step 1

The soil that surrounds a pile is substantially disturbed when pile is driven in normally to lightly over consolidated clay, the state of stress state is changed, and huge excess pore pressures can be developed.

-- Pile in Sand (friction and end bearing) Make calculations to determine the Allowable Load for a 14-inch square precast concrete pile that is driven into a dense medium to fine sand deposit with = 36 deg. and y = 125 pcf. The pile is driven to 85 ft. depth, and there is still 40 ft. of sand below the pile tip. Groundwater is 6 ft. below ground surface. You are to assume that a static pile load test will be performed on one representative pile for this project. Use the limiting depth and limiting pressure approaches for end bearing and for side friction. State the K and 8 values you use, and justify.
