Caution should he exercised in using these shear <br />strength parameters for applications involving normal stresses outside the range of stresses covered by the test series. The value of R the coefficient of correlation. provides an indication <br />of how well the best -fit shear strength parameters match the test data. <br />(3) The large displucetnent shear strength (t was calculated using the shear force measured at the end of each test. <br />©1943 GcoSyntec Consultants <br />
