Would Rendezvous With Rama count? It's not a tomb, and sci fi, but it was huge.
I remember reading the non-fictional story of Howard Carter and the discovery of Tutankhamun's tomb and finding it fascinating, but I don't recall what the book series was called. Something about egyptologists.
The Tomb of Horrors novelization isn't too bad.
Sorry for the necromancy, but I had to note that I'm STILL waiting for the third book of this trilogy. Dammit.I think Greg Costikyan's Another Day, Another Dungeon has a significant dungeon in it. Been too long since I read it, though.
