The soil water characteristics curve of a soil sample is shown in the following figure. According to consolidated drained tests on saturated specimens of this soil, the shear strength parameters are obtained: c' 10 kPa and -35. Calculate the unsaturated shear strengths of the soil for the following matric suctions: 40 kPa, 120 kPa and 240 kPa. 100 90 80 70 60 50 40 30 20 10 1000 10 100 10000 Matric Suction (kPa) Degree of Saturation (%) The soil water characteristics curve of a soil sample is shown in the following figure.
