The Retaining Wall module window is comprised of three panes. The left hand pane contains four input tabs, the center pane contains two output tabs, and the right hand pane contains the design summary and report navigation tree.
Project Input Tab
Name: Input a name for the retaining wall. This is for your information only, and is only used for the text report.
Date: Input a date for the retaining wall. This is for your information only, and is only used for the text report.
Description: Input a description for the retaining wall. This is for your information only, and is only used for the text report.
Backfill Lateral Earth Pressure Theory: Choose a lateral earth pressure theory to use. The options are explained in the theory section.
Include Bearing Pressure: Indicates whether the bearing pressure should be included in the analysis as a force. This will be represented as a distributed load acting on the footing.
Include Sliding Pressure: Indicates whether the sliding stress should be included in the analysis as a force. This will be represented as a distributed horizontal load acting on the bottom of the footing.
Properties Input Tab
Stem
Height: The height of the stem measured from the surface of the backfill.
Thickness: The thickness of the stem at the top of the retaining wall.
Change in Toe: The total tapering amount of the toe, measured at the base of the stem.
Change in Heel: The total tapering amount of the heel, measured at the base of the stem.
Footing
Thickness: The thickness of the footing.
Toe Length: The length of the toe. Measured from the base of the stem.
Heel Length: The length of the heel. Measured from the base of the stem.
Soil
Depth Backfill: The depth of the backfill. Measured from the surface of the base subgrade.
Slope Backfill: The slope of the backfill surface.
Concrete
Unit Weight: The unit weight of the retaining wall concrete.
Elastic Modulus: The elastic modulus of the concrete.
Sliding Friction Angle: The angle of friction between the retaining wall and the concrete
Backfill
Friction Angle: The angle of internal friction of the backfill soil.
Dry Unit Weight: The dry unit weight of the backfill soil.
System
Length of Wall: The total length of the wall.
