GIVENThe following results are from a consolidated undrained test on clay Test 03 811 55.69 psi 92.24 2 psi FIND

Solution

Solution:-

Test(1)

sin_cu = (₁ – ₃)/(₁ + ₃)

            = (92.24 – 55.69)/(92.24 +55.69)

     sin_cu = 0.247

_cu = 14.3 degree Answer

Cu = sin_cu * ₃/(1 – sin_cu)

       = 0.247 *55.69/(1 – 0.247)

        = 18.26 psi   Answer    

For test 2   

sin_cu = (₁ – ₃)/(₁ +₃ )

              = (54.39 – 27.85)/(54.39 + 27.85)

sin_cu = 0.322

_cu = 18.7 degree Answer

C_u = sin_cu *₃/(1 – sin_cu)

     = 0.322 * 27.85/(1 – 0.322)

C_u = 13.22 psi Answer
