Rock Tunneling with Steel Supports, and Introduction to Tunnel Geology

The purpose of this book is to review briefly the tunnel problems which involve steel support systems, and at the same time to suggest means of solving them.The first section is devoted to engineering geology and contains the geological information which is required for estimating the rock pressure on tunnel supports. This section has been prepared by Kark Terzaghi - an outstanding authority on this subject.The second section is devoted to the relationship between rock behavior, type of steel support, and the method of excavation.The third - analytical methods of design of the supporting structure under assumed loading conditions are discussed.The fourth - a catalog is included containing a description of steel supports which are manufactured by the CSS Co. The design of these supports is based on experience gained in supplying ateel support to several hundred tunnels for over 25 years.This book is intended to be helpful to the designing engineer in the drafting room, the resident engineer on the job, and the contractor, his project engineer and his superintendent.
