CEEN 641 – ADVANCED SOIL MECHANICS HOMEWORK ASSIGNMENT #9 1. Determine the internal pore water pressure for the soil sample shown below after it is brought to the surface. Ideally assume that no drainage or change in moisture content occurs. 2. A specimen of soil was isotropically consolidated in a triaxial cell with a chamber pressure of 40 psi and then sheared in a drained manner. Assuming φ = 28º and c = 0, by how much does the axial stress have to be reduced to produce failure by axial extension? 3. Two specimens of silt are consolidated in a triaxial cell to initial conditions of

Unformatted text preview: v = 900 psf and K o = 0.5. The first specimen is slowly sheared drained to failure by maintaining the axial stress v constant and increasing the chamber pressure h to 3050 psf. The second specimen is slowly sheared drained to failure by maintaining the axial stress v constant and decreasing the chamber pressure h to 93 psf. Determine the shear strength parameters and c.
