Properties of settings

Volume weight of water:

Volume weight of water

[Default: 0.00000981 N/mm³]

(The volume weight of water is used in calculation of the neutral soil reaction of soil below water level, which in turn is used for determination of the Top soil reaction [RVT], Sub-soil bearing capacity [RVS] and Neutral/Real top soil load [SOILNB].
In calculation of the neutral soil reaction of soil below water level the volume weight of water is distracted from the saturated volume weight of the soil to compensate for the water buoyancy.)

Accuracy percentage:

Half band width accuracy allowance percentage for soil mechanical parameters

> 0. and < 50.

[Default: 5.]

(The half band width accuracy percentage is used directly in tables: Horizontal soil stiffness [KLH], Downward vertical soil stiffness [KLS], Longitudinal soil friction [F], Sub-soil bearing capacity [RVS] and Top soil reaction [RH].)

Pipeline temperature:

Pipeline operational temperature

Prescribed name

[Default: Cold]

(The pipeline operational temperature can be set to either 1)Cold or 2)Warm.
The answer is used as table entry for the soil mechanical uncertainty values specified in NEN3650.)

State of soil compression:

State of soil compression

Prescribed name

[Default: Badly packed]

(The state of soil compression of the trench filling can be set to either 1)Well packed or 2)Badly packed.
The answer is used as table entry for the soil mechanical uncertainty values specified in NEN3650.)

Calculation methodology:

Calculation methodology

Prescribed name

[Default: Use updated NEN3650-1:2012]

(The Calculation methodology can be set to either 1)Use original NEN3650-1992 or 2)Use updated NEN3650-1:2012.
The Calculation methodology determines the way the mechanical soil values will be calculated (see also Calculation).)
