Ever needed a retaining wall in your site model? It's easier than you think. Here's one example.
In the image below, note that the pond and roadway are overlapping:
A quick look at the profile analysis tool shows that the pond is actually undercutting the road.
We want to add a retaining wall between the road and the pond.
The process we will use for this situation is :
NOTE: This does not design a retaining wall of course. It models the face of the wall as a surface in our design. The specifics of the actual retaining wall design would require a structural engineering approach. Our surface design could be used by the structural engineer to set wall elevations however.
I have drawn two lines for the wall. The red line will represent the top of the wall and the green line will represent the bottom.
Create a new retaining wall object (Modeler > Object > New)
Now, add the top of wall element with the New element tool (Modeler > Element > New/Edit)
We will compute the base of the wall at a slope from the Pond bottom.
Switch the New element tool to the Slope/Offset Option
Finally we need to make sure the FIFO List is in the proper order to give the correct result. (Modeler > Model > Edit)
The order of the marked objects is important. Road C must be after Pond 1 so that the Road slopes will flow into the pond. Retaining wall 1 must be last in order to cut off the Road slopes which spill into the pond and form a wall.
