Specification of soil support angle function at bottom of cross-section, specified along pipeline axis (Input Table)

Data description/conditions:

Identifier (1): (toggleable)

Identification name of data reference point

Required

ANGMIN:

Minimum support angle for soil reactions less than a minimum value for the ratio vertical sub-soil reaction/soil bearing capacity

≥ 15. and ≤ 180.

[Default: 70.]

ANGMAX:

Maximum support angle for soil reactions greater than a maximum value for the ratio vertical sub-soil reaction/soil bearing capacity

≥ 15. and ≤ 180. / ANGMAX ≥ ANGMIN

 

[Default: 180.]

RVSL:

Ratio value vertical sub-soil reaction/soil bearing capacity at which the function curve starts

≥ 0. and ≤ 100.

[Default: 50.]

RVSH:

Ratio value vertical sub-soil reaction/soil bearing capacity at which the function curve ends

≥ 0. and ≤ 100.

[Default: 100.]

CURVE:

Specification of curve shape between RVSL and RVSH

Prescribed names:
Sinus = sinus-curve
Linear = linear-curve
Parabola = parabolic-curve

[Default: Sinus]

 

 

Note 1:

It is notified explicitly that this specification differs from all other similar specifications (except in table SWEIGH) , because the specification of the function is a constant over specified areas, meaning there is no interpolation of elements data between two reference points.
