Residual Strength Tests, Paraitinga and Paraibuna Dams, Brazil.
Abstract
The residual strengths of two micasceous soils from Paraitinga and Paraibuna damsites, Brazil, were determined using multistage annular shear tests. Tests were conducted under three normal loads, 1.1, 3.1, and 9.1 kg/sq cm. Test specimens were densely or loosely compacted (i.e., 100 and 90% of maximum standard density) prior to shear. Test results show that the initial specimen density has no effect on the residual shear strength Phi sub r prime values. In the case of both materials, Phi sub r prime was practically equal for both the densely and loosely compacted specimens. The Paraitinga material exhibited a slightly higher Phi sub r prime value than the Paraibuna materials, 28.0 versus 26.7 deg, respectively.
