Braced Ratianing Wall
Visual Slope can detect what type of brace it is. If it is a multi-braced retaining wall, Visual Slope will allow the user to select the different types of earth pressure - active, at rest, program-defined, and user defined.
The program defined earth pressure is based on: 0.65rHKa
The user can also use the user defined earth pressure. The user can type elevations and earth pressure values into the input box. The pressure value is positive if the pressure is acting on the back of the wall, and is negative if the pressure is acting on the front of the wall.
If a user defined pressure is used, all other pressures, such as surcharge pressure and water pressure, will be ignored.
For a multi-braced retaining wall, the user can select With or Without Embedment. If the Automatically-Adjust-Tieback option is selected, Visual Slope will adjust the tieback free length so that the bonded zone will be beyond the failure zone and it will adjust the bonded length to meet the factor of safety requirement.
Bottom Heave
Visual Slope also adjusts the embedment so that the retaining wall will have an adequate factor of safety against the bottom heave.
