Our 24' round AG is partially buried. We made SURE that it was warranted for that and got that clearly stated in writing before we purchased the pool. The walls of the pool we bought are coated with an epoxy resin and assembled with all stainless steel fasteners. The installers back filled with clean dirt (no rocks, roots or other junk). Being in the deep South, we have red clay soil that compacts tightly.
We also put a border around it, 1 1/2 feet away from the pool wall, put down landscape fabric then put 2 inches of tiny pea gravel on top. That lets splashes drain away and helps prevent things from growing up against the pool wall (you don't want things growing against the walls and spreading roots under the liner). It also keeps the red clay from spattering on the lower part of the walls and staining them. (That red clay stains pretty much whatever it gets on!)
Even with the fabric/pebbles, we spray the border with ground clear and sprinkle ant pellets around it a couple times a year. It looks just as good as when it was installed five years ago!
Of course, you should follow the advice of your pool manufacturer.
Enjoy!
