Question

Assuming that the shear area remains constant during the test, determine the effective cohesion and effective friction angle from these test results. What values of these parameters would you expect? Are the test results consistent with your expectations? What values would you use for design?

A series of direct shear tests has been performed on a dense well-graded sand. All tests
were performed on 3.00-in. diameter, 1.25-in. tall cylindrical specimens, and were run
slowly enough to produce the drained condition. The results of these tests are summarized
in the following table:
Test Number Normal Load (lb) Shear Load at Failure (lb)
84
159
319
123
2
100
200
400
