Specifies the factor by which the transverse ultimate load is multiplied. This option displays only when you select CAESAR II Basic Model in the Soil Model Type list.

This value is used in the soil restraint equations to generate restraint ultimate loads and stiffnesses. The default value is 8. This number can be reduced depending on the degree of compaction of the backfill. Backfill efficiency can be approximated using the proctor number, defined in most soils text books. Standard practice is to multiple the proctor number by 8 and use the result as the compaction multiplier.
