Question

Q3. A site investigation is to be made for a pad foundation that would carry a load of 2500kN including weight of footing. The base dimensions are (3.0mx2.0m). The foundation will be built on a layered soil profile as shown in the figure below. Estimate the depth of boreholes by the De Beer rule (35 points).

Step 1

First, we need to calculate the total weight of the footing. The weight of the footing can be calculated by multiplying the volume of the footing by the unit weight of the soil. Volume of the footing = length x width x depth = 3.0 m x 2.0 m x 1.5 m = 9.0 Show more…
