What is the coeffcient of horizontal subgrade?

[DaveVikingPE]

That is, what's "n sub h"?

The definition is elusive. I told someone to think of it as a horizontal spring constant of soil, but that didn't seem to have any meaning and, semi-lazy me, I haven't mined deep enough. Thanks in advance to anyone with insight, etc.

Now THAT was quite useful.

Most of all, it tells me that I am not wrong when I tell someone to get a better answer from a geotechnical engineer.
