Civil Engineering

A series of consolidated, undrained triaxial tests were carriedout on specimens of a saturated clay under no back pressure. Thetest data at failure are summarized:

Confining pressurekPa          Deviatorstress kPa    Pore water pressure kpa

150                                                   192                                    80

300                                                   341                                    154

450                                                   504                                    222

  1. Draw the mohr circles and find the cohesion and friction anglein terms of effective stresses.
  2. Compute Skempton’s A-Parameter at failure for all threespecimens
  3. Is the soil normally consolidated or overconsolidated?Why?
  4. Another specimen of the same clay that was consolidated under acell pressure of 250kPa was to a consolidated , drained trialdrained triaxial test. What would be the deviator stress atfailure.
