Refer to Problem 6.1. Using Eqs. (6.3) and (6.29), estimate the average stress increase (Δσav) below the center of the loaded area between depths of 3 m and 6 m. 6.1 A flexible circular area is subjected to a uniformly distributed load of 150kN/m2 (Figure 6.2). The diameter of the load area is 2 m. Determine the stress increase in a soil mass at points located 3 m below the loaded area at r = 0. 0.4 m, 0.8 m, and 1 m. Use Boussinesq’s solution.

a sample of soil is subjected to two mutually perpendicular direet stresses of 80 kN/m² tensile and 50 kN/m compressive, together with a shear stress of 30 kn². The shear couple acting on planes carrying the 80 kN/m? stress is clockwise in effect. Find numerically: i) 01, and o3 ii) The maximum shear stress. iii) The direction of the planes on which these stresses act. Confirm your answer by means of a Mohr's stress circle diagram, and from the diagram determine the magnitude of the normal stress on a plane inclined at 20° counterelockwise to the plane on which the 50 kN/m? stress acts.
