GGU-RETAIN: "Lateral pressures" menu item
If, in addition to the diverse possibilities for determining earth pressure on the wall, you also need to take additional surcharges into consideration, this is where to enter them.

The number of lateral pressures can be modified using the "x lateral pressure(s) to edit" button. Then enter the ordinates in metres from the top of the wall or as absolute heights, and the values for the lateral pressures.
The lateral pressures can be represented by permanent or variable loads, water pressures or passive earth pressures. The characteristic values are entered and are automatically multiplied or divided by the appropriate partial safety factors.
