Practice Question: Calculate Stress at Depth Below Soil Surface

NCEES Civil PE Specification Soil Mechanics: Effective and Total Stresses


Problem

 A 6-foot by 8-foot foundation imposes a 150-kip load on a soil surface (including self-weight).

Determine the approximate value of stress 10 feet below the soil surface due to the foundation load.  Assume a 2:1 vertical distribution of stress.
