RockRetainingWall

Attachment

The attachment point is at either the rock face or a distance away from the way location based on the Front Link input parameters.

Input Parameters

Note: Note: All dimensions are in metres or feet unless otherwise noted. All slopes are in run-over-rise form (for example, 4 : 1) unless indicated as a percent slope with a “%” sign.

Parameter	Description	Type	Default

Target Parameters

This section lists the parameters in this subassembly that can be mapped to one or more target objects. For more information, see To Specify Corridor Targets.

Parameter	Description	Status
Existing Surface	Name of the daylighting surface. The following object types can be used as targets for specifying the surface: surfaces.	Optional
Top of Wall	May be used to override the top of wall level of the rock wall. In order to be used, the Fixed Height Input Parameter must be set to No. The following object types can be used as targets for specifying the level: profiles, 3D polylines, feature lines, or survey figures.	Optional
Bottom of Wall	May be used to override the bottom of wall level. The following object types can be used as targets for specifying the level: profiles, 3D polylines, feature lines or survey figures.	Optional

Runtime Logical Assignments

None.

Output Parameters

None.

Behavior

The initial point is set at the attachment point. The front link is built if Use Front Link is set to Yes. The rock wall is then built.

If Use Fixed Height is set to Yes the rock wall is built using the input parameters. If the Bottom of Wall profile is set then the top of wall height is determined by the Bottom of Wall profile level plus the fixed height. The top of wall target is not used.

Cut Condition:

If Use Fixed Height is set to No the rock wall is built using the input parameters. The Top of Wall Target controls the top of wall level. If the Top of Wall Target is not set then the Top of Wall level is the existing ground level at the inside edge of the wall.

Fill Condition:

If Use Fixed Height is set to No the rock wall is built using the input parameters. The Top of Wall Target controls the top of wall level. If the Top of Wall Target is not set then the Top of Wall level is the distance between the attachment point and the Rock Wall Top Extend in Fill input parameter.

In all conditions the wall height is calculated and compared to the Maximum Retaining Wall Height. If the value is exceeded then an error message is sent to the Event Viewer.

Layout Mode Operation

In layout mode, this subassembly draws the rock retaining wall with the input parameters.
