Importance of Geological Information as a Factor in Tunnel-Lining Design
Published:January 01, 1959
The writer outlines the progressive requirements of the engineer for geologic information as a project develops and defines the need for certain quantitative information in final design stages. Methods of obtaining and evaluating such information are discussed. Equations are given which illustrate the role that the modulus of elasticity of the rock plays in proportioning the elements of a pressure-tunnel lining. This effect is portrayed graphically by a dimen-sionless chart and is exemplified by computations showing the specific effect upon steel-lining thickness. In conclusion, the importance of developing more reliable and simpler methods of determining the elastic properties of rock is stressed.

Engineering Geology Case Histories Number 3: Symposium on Rock Mechanics
Prepared by the Case Histories Committee for the Engineering Geology Division of the Geological Society of America, these histories are intended as reference material for the practicing geologist and for the college student. The Symposium on Rock Mechanics, edited by Parker D. Trask, is the third volume on the series. It contains the following papers: Some engineering studies of rock movement in the Niagara area; Rock mechanics in the investigation and construction of T.1 Underground Power Station, Snowy Mountains, Australia; Importance of geological information as a factor in tunnel-lining design; and Effect of the elastic properties of rocks on civil-engineering design.
