GabionWall

The GabionWall subassembly creates a Gabion Wall. The Gabion Wall is based on Caltrans Standard Plan D100A.

You should verify that the dimensions used match your interpretation of the standard plan.

Case: Attachment at Top of Wall

Case: Attachment at Bottom of Wall

Attachment

The attachment point is at the inside edge of the initial cut or fill slope. This component can be attached to either the left or right side.

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
Side	Specifies which side to place the subassembly.	Left / Right	Right
Stepped Offset Distance	Face offset distance for gabions	Numeric, positive	0.5 ft 0.15 m
Has Surcharge	Has soil above the wall	Yes / No	No
Gabion Gradient	Gradient of gabion	Numeric	5 (%)
Attachment Place	Attachment place on wall	TopOfWall / BottomOfWall	Bottom Of Wall

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
Top of Wall Level	May be used to set the top of wall level when the attachment point is set to bottom of wall. The following object types can be used as targets for specifying the level: profiles, 3D polylines, feature lines or survey figures.	Required when attachment point is Bottom of Wall
Bottom of Wall Level	May be used to set the bottom of wall level when the attachment point is set to top of wall. The following object types can be used as targets for specifying the width: alignments, polylines, feature lines or survey figures.	Required when attachment point is Top of Wall

Runtime Logical Assignments

The dimensions of the gabion layers are set within the subassembly based on the current layer and the height of the gabion wall.

Output Parameters

None.

Behavior

The initial hinge point is set at the attachment point. The gabion wall height is then calculated from the attachment point and the top of wall or bottom of wall profile. The maximum number of gabion layers is 10 and is split up into 3 ft (1 m) layers. Gabion wall height is rounded up to an even number of layers.

Each gabion layer is then built based on the input parameters.

Layout Mode Operation

In layout mode, this subassembly draws the maximum 10 gabion layers.

Point, Link and Shape Codes

The following table lists the point, link and shape codes for this subassembly that have codes assigned to them. Point, link or shape codes for this subassembly that do not have codes assigned are not included in this table.

Point, Link or Shape	Code	Description
P1-PX	Gabion	Gabion point, applied to all points
L1, L5	Datum	Repeats for each layer
L3, L6	Top	Repeats for each layer
SX	GabionX	X is replaced by the current gabion layer

Coding Diagram

The first two gabion layers are labeled in the following illustration. The other gabion layers are similar.
