It is something the derives from the so called Torres bracing. It is a very general and imprecise description, because many luthiers develop their own bracing scheme.
So, if by "Torres bracing" you mean exactly reproducing brace dimension and spacing exactly like Torres used to do, then the answer is no. Especially because Torres himself tried many different bracing patterns.
On the other hand, if by "Torres bracing" you mean something vaguely resembling Torres bracing patterns, with huge areas of variation, then the answer is yes.

You'll have more luck with googling fan bracing, which is the general term. There are alternative schemes (various forms of lattice, Kasha, and so forth) but the vast majority of classicals is fan braced.
