Compose soil data model

 

Function ready condition: All '(C)onditional'-input tables tested or empty. The start condition of the function is the function ready condition, because all tables may remain empty. As soon as one of the tables contains data the function condition changes to the DATA condition, and all 'C' tables shall contain data. In case of NO SOIL (empty tables) the function must be processed as well and will get the LOCKED status. Result data tables will not be produced in that case.

 

Function error condition: 4 error conditions, 9 warning conditions, 3 informational messages, 3 messages

Errors:

E32-001:

Soil model inconsistent.

Soil parameters may be zero, but depending on the value of the other soil parameters this error may occur.

•output tables with such a parameter value = 0. will be questioned (with related parameter value = 0. will be indicated [Error!])

•output tables with related parameter values will be questioned

•other output tables will be produced

 

Also see possible soil parameter value combinations.

E32-002:

Overlapping slack areas.

SLACK areas overlap.

•output tables will be questioned with overlapping slack values indicated [Error!]

E32-003:

All slack values should be greater than zero (or zero).

All lateral slack values should either be > 0. or equals 0. The axial slack may be 0. When the axial slack is >0., all lateral slacks should also be > 0.

•output table LATSOIL will become questioned

•output table AXSOIL will not be produced

 

Slack values can also programmatically be set to no slack (I32-002 will be reported). E.g. when the RH is zero, the horizontal slack will be set to no slack. So even if H-SLACK in table SLACK is assigned a value greater than zero this error might occur.

In case E32-003 is reported, E32-001 is also always reported, and the calculation will stop only after that error.

E32-004:

SLACK with zero RVT.

Defining slack values without having top soil is not allowed.

•output table LATSOIL will become questioned, with the parameter RVT indicated [Error!]

•output table AXSOIL will not be produced

Warnings:

W32-001:

Defunct.

W32-002:

Defunct.

W32-003:

Extreme 'KLH' / ('KLT' or 'KLS') ratio.

Ratio KLH/KLT or KLH/KLS not between 1:20 and 20:1.(1)

W32-004:

Extreme 'RH' / ('RVT' or 'RVS') ratio.

Ratio RH/RVT or RH/RVS not between 1:20 and 20:1.(1)

W32-005:

'SLACK' over full soil length.

A SLACK space is specified over the whole soil supported pipeline length.

W32-006:

A horizontal soil parameter does not meet the criterion of the vertical parameters.

A horizontal soil mechanical parameter is less than the vertical parameter at the top of the pipe or exceeds the vertical parameter at the bottom of the pipe.

(Originally the horizontal (HOR) value was less than the bottom (SUB) value and greater than the TOP value. But since the formulae for calculating the soil mechanical parameters are modified and improved (?) this is no longer (always) true)

W32-007:

Geometry changed, soil wizard generated data may be out-of-date.

Soil model wizard data is based on the geometry of the pipeline defined in DF2 and DF3.1. Once soil data is generated by the wizard and the user changes the geometry (e.g. POLYDIF or G-LEVEL in DF2, or DIAM in DF3.1) this warning will be reported.

W32-008:

Soil data has changed after running the soil wizard.

When soil model wizard generated data is changed 'manually' (e.g. changes in input table KLS) this warning will be reported.

W32-009:

The maximum value of KLS is over 100 times the minimum value.

The maximum of the downward vertical soil stiffness (KLS) is more than 100 times the minimum of KLS.

(This warning is only given if the analysis type is “NEN 3650-2”. In all other cases message I32-003 is given instead.)

Informational messages:

I32-001:

Soil parameter 'name' in table 'name' is set to no soil.

A soil parameter has been specified over a pipe section without soil.

(title1 = soil parameter (column name) in soil data output table title2 = soil data output table LATSOIL or AXSOIL.)

The presence of soil is governed by the specification of the RVS, meaning for those parts of the pipeline where the RVS = 0 all other soil parameters will be treated as being zero as well, regardless of any value in the other tables concerned.

I32-002:

Slack parameter 'name' in table 'name' is set to no slack.

A slack parameter has been specified over a pipe section without soil. Also see E32-003.

I32-003:

The maximum value of KLS is over 100 times the minimum value.

The maximum of the downward vertical soil stiffness (KLS) is more than 100 times the minimum of KLS.

Messages:

M32-001:

Defunct.

M320/2:

KLS_max > 100 * KLS_min.

The maximum of the downward vertical soil stiffness (KLS) is more than 100 times the minimum of KLS.

(This message is given if the analysis type is other than “NEN 3650”. In case of NEN 3650 calculations warning W32-009 is given instead.)

M32-003:

Soil removed from inner pipe (nodes 'node1' - 'node2')

The soil properties from the inner pipe section of a SiS pipeline are removed.
