Variable Stiffness

The soil stiffness can be specified to vary with depth. This property is defined in the dialog "Edit soil parameters" by choosing "Stiffness increasing with depth". Entering parameter kd ensures that the finite elements will be assigned an individual value of Young's modulus depending on their depth (vertical distance from the terrain in the first construction stage) according to the equation

where:

E0

-

Young's modulus on terrain [MPa]

h

-

depth [m]
