NCEES Civil PE Specification Soil mechanics: Settlement

Problem

For the shown soil strata and shallow wall foundation show, calculate the immediate settlement using the elastic method considering the following data:
• No Groundwater encountered.
• Pressure at foundation level due to Wall & Footing = 2000 psf
• Assume wall footing is continuous.
• Soil is dense fine sand

Solution

Answer: B) 0.9 inch

Refer to the PE Civil Reference Handbook Section 3.5.2:

\(\delta_v=C_{d} \Delta p B_{f} \frac{((1-\upsilon^2 ))}{E_{m}}\)

\(\Delta p = Change\ in\ stress\ at \ foundation\ depth \\\)
