Engineering Rock Mechanics
John P Harrison, John A Hudson
When I took rock mechanics at Berkeley we used Prof. Goodman's book (of course), but I have found this book to be far more user friendly and complete. Although an understanding of geology and earth processes is essential for the subject to be understandable, this book and the accompanying book of worked problems will teach you the subject well and thoroughly. I just wish they'd make the accompanying book of worked problems in paperback becuase it's too expensive.
