A calculate the pore water pressure developed in the


A NC clay has an effective friction angle of 28o and zero effective cohesion. A CU test conducted on the clay gave the following results:

  • Confining stress = 105 kPa.
  • Deviator stress at failure = 97 kPa

 

a) Calculate the pore water pressure developed in the specimen at failure.

b) What would the deviator stress at failure have been if a CD test had been conducted with the same confining pressure (i.e., 105 kPa)?
