I saw a pool here in Florida which was left drained by unthinking, absentee owners. It rose up like a boat above ground level and then listed to one side.

Simply put, there's always underground movement and water pressures underneath pools. The weight of the water in a filled pool obviates this problem.

Thanks for the replies. I have never owned a pool and just figured it was a concrete-lined hole in the ground.
