A sand sample with = 1.95, λ = 0.04, M = 1.4, is consolidated in triaxial apparatus under
axial stress = 200 kPa and radial stress or = 50 kPa then sheared under standard triaxial test.
If the specific volume before shear is vo= 1.73. What will be the undrained shear strength of
sand and the magnitude of backwater pressure so that the water will not cavitate during
undrained failure.
1. A Sample of Clay is isotropically normally consolidated to a cell pressure of 350kPa. The sample
was then sheared (standard) in a drained state. Calculate values of q, p', and v at failure if the
soil constants were:
M=0.88, N=2.88, T=2.76, and λ=0.16
Three samples of loose sand were tested under consolidated undrained conditions. The failure stresses and excess pore water pressure for the soil sample is given below:
Cell pressure = 212 kpa
Deviator stress = 128 kpa
Pore water pressure = 81 kpa
Determine the drained angle of inclination of failure plane in degrees.
