Horizontal soil stiffness [KLH]

Horizontal soil stiffness [KLH]

Calculation of Horizontal soil stiffness

The soil range of importance for the Horizontal soil stiffness is from the pipeline axis to 1.5 diameter under the pipeline axis, which is the same as for the Downward vertical soil stiffness.

NEN3650-1992

Using the NEN3650-1992 methodology, the Horizontal soil stiffness is determined using the following equation:
