Specification of downward vertical soil stiffness along pipeline axis (Input Table)

Data description/conditions:

X-P:

X-coordinate of data reference point

None / Required ¹

(X-P values should be increasing. Column may be toggled to AX-L, AX-LP, NODE, ELEM or IDENT, see toggling data tables.)

KLS1:

Downward vertical soil stiffness just before and at data reference point

≥ 0.

(The value given for KLS1 on the first data table line is valid for every value of X less than or equal to X-P(1))

KLS2:

Downward vertical soil stiffness just after data reference point

≥ 0. / Undefined

(The value given for KLS2 on the last data table line(n) is valid for every value of X greater than X-P(n). If KLS2=UNDEFINED it is assumed KLS2 = KLS1)

UNCF-L:

Uncertainty factor resulting in lower soil parameter kls

≥ 1. / Undefined if UNCF-H is specified

[Default: 2.0]

(If UNCF-L = UNDEFINED it is assumed that UNCF-L = UNCF-H. UNCF-L is used when the uncertainty in table UNCER is set to Low)

UNCF-H:

Uncertainty factor resulting in higher soil parameter kls

≥ 1. / Undefined if UNCF-L is specified

[Default: 2.0]

(If UNCF-H = UNDEFINED it is assumed UNCF-H = UNCF-L. UNCF-H is used when the uncertainty in table UNCER is set to High)

VARAR:

Half band width accuracy allowance percentage for soil parameter

> 0. and < 50. / Undefined if KLS1=KLS2=0.

[Default: 5.]
