Civil Engineering Questions & Answers

  Dfine consolidated undrained angle of shearing resistance

A sample of saturated soil was consolidated under an all-around pressure of 60 lb/in2. The axial stress was then increased without permitting drainage. The sample failed when the axial deviator stress reached 50 lb/in2.
