Notes- (1) Sliding occured between the clay borrow soil liner (SLC -4) and the textured side ofthe gcometnbrane.
(2) The reported total - stress shcar strength parameters for each test series were determined from a straight line drawn from the origin through the lest data. Caution should be exercised in using these
strength parameters for applications involving normal stresses other than the normal stress used in the test.
