Cohesive

The following parameters are available for Cohesive soil layers:

• Undrained Shear Strength
• Modified Bearing Capacity Factor, Nc’
• Adhesion Factor for Shaft
• Unit Cylindrical Shear Limit

Nc’ is Meyerhof’s (1951) modified bearing capacity factor.

The Adhesion Factor for Shaft is applied to unit skin calculations on segments within the shaft. To enable it, ensure that Include Shaft Adhesion/Friction is enabled from the Capacity Calculations tab of the Project Settings.

The Unit Cylindrical Shear Limit provides an upper bound to the results of cylindrical shear and values shall not exceed this amount. The default value is set to 10000 so as to not preemptively cap the results at the limit.
