The data shown in Fig P13.58 are obtained from several CU tests on a saturated clay which has an OCR of 10 and a pre-consolidation stress of 800 kPa. It is assumed that these results are valid for all compression stress paths on this clay. You are going to run a special stress path test on this clay. After consolidation at σ'vo, the cell pressure will be increased in such a way that ˆ†Ïƒ3 = 0.2 ˆ†Ïƒ1 until failure occurs. For this special stress path test, fill in the table below and plot the total and effective stress paths. (After C.W. Lovell.)?
