GRS MSE wall component
Typical Cross Section
Parameters
| VtOffset | Vertical offset from the component attachment point (CL) to the start of the horizontal offset measurement. | |
| HzOffset | Horizontal offset. If wall to be at rd edge, rd subgrade width. Super and widening applied. | |
| FaceHt | Height of facing element. | |
| FaceWidth | Width of facing element. | |
| FaceOffset | Horizontal setback of each face unit from front of previous. | |
| bFixedToe | 1 forces toe to be set at elevation (ToeOfWallElevOrDat), 0 toe elevation is a function of topo, elevation. | |
| ToeOfWallElevOrDat | Elevation of the wall toe (bFixedToe=1) or elevation to set datum of longitudinal steps. | |
| LvlCrsOutOffs | Leveling course outside offset. | |
| LvlCrsInOffs | Leveling course inside offset. | |
| LevelingCourseHt | Depth of leveling course material. | |
| LevelingCourseCut | Cut slope of leveling course material. | |
| CriticalBFillSlp | Slope that delineates critical backfill material and tie back length. | |
| CritBackFillBtmWdt | Width of critical backfill material at bottom of wall. This also delineates tie back length. | |
| MinWallEmbedment | If not a fixed toe, minimum depth of wall below stripped topo. | |
| TieBackVtSpacing | Vertical spacing for primary tie back layers | |
| MinTieBckCover (advanced) | Minimum critical backfill cover over top tieback. | |
| Fillslope_OtherSid (advanced) | Fill slope for the other side of the road. Only useful if the rockfill extends beyond the width of the road top. | |
| RoadSGWidthOpp (advanced) | Road subgrade width on opposite side of attachment point (CL). |
