Questions and Answers
What is the increased earth pressure immediately beneath the footing?
The increased earth pressure immediately beneath the footing is equal to the load divided by the area of the footing, which is 25 tons per square foot.
What happens to this additional pressure further down in subsequent soil layers? Explain why...
The additional pressure decreases with depth due to the weight of the soil above compressing the soil below. This is known as the Boussinesq's theory of stress distribution.
What is the total effective stress at a depth of 10 ft if the soil layer has a unit weight of 100 pcf?
The total effective stress at a depth of 10 ft is the weight of the soil and the footing above it, which is 10 ft x 10 ft x 100 pcf + 50 tons = 105 tons.
