Front Face Resistance
The "Front face resistance" frame allows us to specify the terrain shape in front of the structure and parameters of front face resistance. The selected shape with a graphic hint of input values is displayed in the left part of the frame. The terrain shape can be edited either in the frame by inserting values into input fields, or on the desktop using active dimensions.
Combo lists in the frame allow selecting the type of resistance and a soil (from the soils introduced in the "Soils" frame). The terrain surcharge magnitude and soil thickness (above the wall lowest points) can also be specified.
The resistance on a structure front face can be specified as the pressure at rest, passive pressure, or reduced passive pressure. The resulting force due to the reduced passive pressure is calculated as a resultant force caused by pressure at rest and passive pressure multiplied by corresponding coefficients.
