Chapter 3, Problem 3.5QPP

A site is underlain by a soil that has a unit weight of $187{\text{kN/m}}^{\text{3}}$ above the groundwater table and $19.9{\text{kN/m}}^{\text{3}}$ below. The groundwater table is located at a depth of 3.5 m below the ground surface. Compute the total vertical stress, pore water pressure, and effective vertical stress at the following depths below the ground surface:

a. 2.2 m

b. 4.0 m

c. 6.0 m
