Rock undrained shear strength
Webuncorrected N value and undrained shear strength is illustrated in Figure 3. Hypothesis testing indicates that there is little, if any, correlation of significance between these two parameters. The R2 value of less than 0.2 indicates that there is no significant association between the uncorrected N value and undrained shear strength.
