Problem 5 (20pt) A specimen of saturated clay with effective strength parameters o' = 30° and c' = 7 kPa was placed in a triaxial test and subjected to the following load sequence: a. A cell pressure of σ1 = 03 = 200 kPa was applied with the drain open. b. The drain was closed and the cell pressure 03 was increased by 10 kPa. c. With the drain still closed, the axial stress was further increased until failure of the specimen occurred when o1f = 534 kPa. Fill in the table below to indicate total stress, pore pressure, and effective stress acting on the specimen after each stage of loading. Show all of your work on a separate page. σ₁ (kPa) 03 (kPa) u (kPa) o'ı (kPa) σ'3 (kPa) a. b. C.
