Abstract

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.
