1. The following results were obtained at failure in a series of drained triaxial tests on fully saturated clay specimens originally 38 mm diameter by 76 mm long. The minor and major principal stresses are calculated and presented in the table below (You are responsible of learning this procedure for the MT exam).

1) Undrained triaxial tests were conducted on clay specimens with diameter and height of 38 mm and 76 mm respectively. The test results are shown in Table 1. Plot the typical stress- strain relationships, and determine the peak shear strength of the tested soil Table 1.

2.If an additional CU triaxial test with pore pressure measurement is to be performed using a ?3 of 250 kPa on a specimen identical to those in last Problem , estimate the deviator stress (?d) and pore pressure (u) of this additional test at failure. What would potentially be orientation of the failure plane in the specimen? The results below were obtained at failure in a series of consolidated-undrained (CU) triaxial tests, with pore pressure measurement, on specimens of fully...
