FAQ

Are the reinforcement elevations measured from the top or from the bottom? From the crest: z = 0 at the top, level 1 is the highest one. The actions therefore grow with z, going down.

Why don't the factors in the card change when I switch the seismic action on? That card is the static combination; the seismic one is generated separately with its own factors (the read-only "Seismic" column). See Combinations.

Why can't the last reinforcement fall exactly at the base? At z = H the Rankine length is zero: change the spacing or the height slightly.

Does the facing inclination enter the checks? No: as in the GSRD desktop program, α defines the shape of the section; the thrust is evaluated on the equivalent vertical wall (conservative with battered facings). The tieback/compound surfaces cover the reinforced-soil behaviour.

What does "design envelope" mean in the Reinforcements tab? Per level: the combination with the lowest FS and the largest total length across the combinations — the length to build.

The figures don't show up in the report. They are captured from the page: run the calculation and open the 2D section / 3D / Stability tabs before generating the document.
