Specification of maximum horizontal soil reaction 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.)

RH1:

Maximum horizontal soil reaction just before and at data reference point

≥ 0.

(The value given for RH1 on the first data table line is valid for every value of X less than or equal to X-P(1))

RH2:

Maximum horizontal soil reaction just after data reference point

≥ 0. / Undefined

(The value given for RH2 on the last data table line(n) is valid for every value of X greater than X-P(n). If RH2=UNDEFINED it is assumed RH2 = RH1)

UNCF-L:

Uncertainty factor resulting in lower soil parameter RH

≥ 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 RH

≥ 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)

CFH1:

Lateral friction factor just before and at data reference point

≥ 0. and ≤ 1. / Undefined

(CFH1*R-LAT is considered as a lateral soil resistance additional to the specified RH. The UNCF factor is not applicable to CFH1.)

(If CFH1 = UNDEFINED , no additional lateral soil resistance is added to the specified initial lateral soil resistance (see Table Description))

CFH2:

Lateral friction factor just after data reference point

≥ 0. and ≤ 1. / Undefined

(CFH2*R-LAT is considered as a lateral soil resistance additional to the specified RH. The UNCF factor is not applicable to CFH2.)

(If CFH2 = UNDEFINED , it is considered to be equal to CFH1)

VARAR:

Half band width accuracy allowance percentage for soil parameter

> 0. and < 50. / Undefined if RH1=RH2=0.

[Default: 5.]
