Unformatted text preview: φ ' crit . Is the sample lightly or heavily overconsolidated? Q5.1 Solution Convert the data to the required format using the following equations (for derivations and justifications, see the main text Section 5.4 etc): γ =1.5 ε a (main text Figure 5.7) t = ( σ ' 1' 3 )/2 (main text Equation 5.1) s' = ( ' 1 + ' 3 )/2 (main text Equation 5.2) φ ' mob = sin1 (t/s') (main text Figure 5.6) q = ' a' r = ar = ac (main text Equation 5.6) p'= cu+q/3 (main text Equation 5.10) p= c +q/3. (main text Equation 5.11) Now, t = ( ' 1' 3 )/2 = ( 13 )/2 = ( ac )/2 = q/2 and s' = ( ' 1 + ' 3 )/2 = [( 1 + 3 )/2]u = [( a + c )/2]u...
