Abstract: The fault element is used to handle soft clay strata in a rock mass.The formulas or clasto-plastic stiffness matrix for the fault element are derived using the constitutive relationship between plastic increment stress and strain.A numerical example of a circular tunnel with soft clay strata in the rock medium are examined.
