RockRetainingWall

The RockRetainingWall subassembly inserts links to create a rock retaining wall to retain soil.

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: All dimensions are in meters 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.

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 elevation 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 elevation: profiles, 3D polylines, feature lines, or survey figures. Optional
Bottom of Wall May be used to override the bottom of wall elevation. The following object types can be used as targets for specifying the elevation: 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 elevation 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 elevation. If the Top of Wall Target is not set then the Top of Wall elevation is the existing ground elevation 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 elevation. If the Top of Wall Target is not set then the Top of Wall elevation 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.
