Specification of longitudinal displacement to develop maximum soil friction specified 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.)

UF1:

Longitudinal soil friction displacement just before and at data reference point

≥ 0.

(The value given for UF1 on the first data table line is valid for every value of X less than or equal to X-P(1))

UF2:

Longitudinal soil friction displ. just after data reference point

≥ 0. / Undefined

(The value given for UF2 on the last data table line(n) is valid for every value of X greater than X-P(n). If UF2=UNDEFINED it is assumed UF2 = UF1)

UNCF-L:

Uncertainty factor resulting in lower soil parameter UF

≥ 1. / Undefined if UNCF-H is specified

[Default: 1.6]

(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 UF

≥ 1. / Undefined if UNCF-L is specified

[Default: 1.6]

(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)
