The relationship curves of and of the samples under the dry density of 1.4 g/cm3 with different water contents, confining pressures, and temperatures. (a) = 1.4 g/cm3, = 5%, = 0 kPa. (b) = 1.4 g/cm3, = 5%, = 1000 kPa. (c) = 1.4 g/cm3, = 5%, = 2000 kPa. (d) = 1.4 g/cm3, = 15%, = 0 kPa. (e) = 1.4 g/cm3, = 15%, = 1000 kPa. (f) = 1.4 g/cm3, = 15%, = 2000 kPa. (g) = 1.4 g/cm3, = 25%, = 0 kPa. (h) = 1.4 g/cm3, = 25%, = 1000 kPa. (i) = 1.4 g/cm3, = 25%, = 2000 kPa.
