Question 7.4 A normally consolidated clay is consolidated under a triaxial chamber con- fining pressure of 495 kN/m² and o = 29. In a Rendulic-type diagram, draw the stress path the specimen would follow if shcared to failure in a drained condition in the following ways: (a) By increasing the axial stress and keeping the radial stress constant. (6) By reducing the axial stress and keeping the axial stress constant. (c) By increasing the axial stress and keeping the radial stress such that o + 20, =const. (d) By reducing the axial stress and keeping the radial stress constant. (e) By increasing the radial stress and keeping the axial stress constant. By reducing the axial stress and increasing the radial stress such that o+20=const.
