Joint Properties Overview

To define Joint Properties (e.g., shear strength, water pressure, joint structure):

1. Select Input Data from the toolbar, the Analysis menu or the right-click menu.
2. Select the Joint Properties tab in the dialog.
3. For a new file, a single default property type will already be defined. If you only require a single property (i.e., all of your joints have the same strength characteristics), then you can simply define the properties (shear strength, water pressure, joint structure) for this one property type.
4. If you need more than one property type (for example: if each of your joints has different strength characteristics), then select the Add button to create additional properties. After adding, click on the new joint property from the left pane. The values shown will be the default properties. You can change them to the desired values. You also have the following options:
• Copy current properties: This will create a copy of the currently selected joint property
• Import from file: This allows you to import joint properties from another UnWedge file. Enter a filename path in the edit box, or select the dialog button to navigate to a file.
5. You can change the default naming of the joint properties, as follows:
• First click on a name in the list
• Then type in the new name in the Name box
6. To define the properties, for each property in the list, click on the property name and enter the following information:
• Shear Strength
• Water Pressure
• Joint Structure Continuity
• Waviness

Assigning Joint Properties

Once Joint Properties have all been defined, you must assign them to the desired joints.

To assign joint properties:

1. Select the Joint Orientations tab in the Input Data dialog.
2. For each joint in the list, assign the desired Joint Property in the Properties column (click in the Properties column, and select the name of a joint property from the drop-list).
