Specifies the value of the soil displacement at which the ultimate upward restraint load is developed. This value is calculated as per the following equation:
dQu - MIN (MULTIPLE OF H) * H, (MULTIPLE OF D) * D
The maximum multiple of the pipe buried depth (H) must be entered here. Typical values:
-
Dense Sand - 0.01
-
Loose Sand - 0.02
-
Stiff Clay - 0.1
-
Soft Clay - 0.2
