WebThe friction angle, d', of a normally consolidated clay specimen collected during field exploration was determined from drained triaxial tests to be 25°. The unconfined compression strength, qu, of a similar specimen was found to be 100 kN/m². Determine the pore water pressure at failure for the unconfined compression test. WebOct 21, 2024 · LRJ (Civil/Environmental) 21 Oct 18 17:15. Generally you cannot use the friction angle to get the undrained shear strength (s u ). This is because s u is equal to the deviator stress at failure (q f) divided by 2 (think of a Mohr circle), which is affected by the pore-water pressure (i.e. contractant versus dilatant behaviour during undrained ...
