Submerged weight of all of the soil that can be present on top of the spudcan. NOTE Backfilling can occur during or after preloading. WBF,o refers to the submerged
weight of the backfilling that occurs up to achieving the preload reaction. WBF,A refers to the submerged weight of the backfilling that occurs after the maximum preload has been applied and held. Both WBF,o and WBF,A can comprise backflow and/or infill. For discussion of the effects, see A.184.108.40.206.4.
