GGU-RETAIN: Variant "Automatically determined section length and bedded toe"

Using this option, you can determine the optimum height of the wall.

First you must define the range of section lengths within which GGU-RETAIN is to find the ideal value.

Enter the maximum and minimum section lengths, as well as a delta section length, in the top group box of the dialog box shown above. This defines the range of lengths from which the optimum length should be selected. The central group box deals with iteration (see explanations in “Theoretical principles: Bedded systems - Variant “Section length fixed and bedded toe””). In the bottom group box, you can define additional iteration criteria, such as maximum displacement of the wall top.
