This book gives a comprehensive account of the theory and practice of engineering geology as it is applied to tunneling in rock. The first four chapters deal respectively with the basics of tunneling; the petrography of unaltered rocks; the petrography of altered rocks (by weathering, deuteric, pneumatolytic and other types of alteration); and rock mechanics. The next chapter is concerned with the processes of rock deformation by earth forces that result in modification of the rock fabric. Attention is drawn to the importance of these forces in tunneling because they can reduce the competency of rocks or affect the circulation of groundwaters and gases. The ways in which groundwaters (including the special problems associated with hot waters) and gases can affect tunneling are described together with the types of geological investigations prior to tunneling (including the use of geological maps, geophysical investigation, remote sensing, aerial photography and core drilling), and the application of the results of such investigations to tunnel planning and design. The final two chapters give in information on tunneling methods and the geological investigations during the construction of a tunnel. /TRRL/
