A consolidated-undrained triaxial test was conducted on dense sand with a chamber-confining pressure of 138 k N/m2. Results showed that ϕ' = 24° and ϕ = 31°. Determine the deviator stress and the pore water pressure at failure. If the sand were loose, what would have been the expected behavior? Explain.
