Problem 5 (24 points) A continuous foundation on a deposit of sand layer is shown in the following figure. The equivalent modules of elasticity (Es) of the soil at different depths have been determined by CPT tests and are shown in the table. y for the sand is 125 lb/ft? The groundwater table is at a great depth. The bearing pressure q = (P +W) / A is known as 2900 lb/ft?. Using the Schmertmann's method, complete the table below and then compute the settlement of the foundation at t= 40 years. Show your process.
