When tunneling through a mountain, the orientation of rock layers dictates the support system. If a tunnel runs parallel to the strike of steeply dipping weak rock layers, the roof is highly unstable. Varghese’s text helps engineers design appropriate rock bolting, shotcrete linings, and steel ribs based on the local geological profile. Highway and Railway Slopes
Engineers must identify rocks not just by name, but by their mineral composition, which dictates weatherability and strength. Varghese breaks down the three primary rock families from an engineering perspective:

A major part of the book is dedicated to site selection for heavy infrastructure. It explains how to choose suitable sites for dams and tunnels by analyzing the underlying geological conditions. 3.6. Earthquakes and Geological Hazards
It masterfully bridges introductory physical geology, mineralogy, and petrology with actionable geotechnical applications. If you share with third parties, their policies apply
"Engineering Geology" by PC Varghese is a valuable resource for civil engineers, providing a comprehensive understanding of the geological principles and their applications in engineering practice. The book covers a wide range of topics, from basic geological concepts to advanced geotechnical engineering principles. We hope that this article will provide a useful guide for civil engineers and students to understand the importance of engineering geology and to access the PDF version of the book.
Most engineering universities provide digital access to textbooks via platforms like ScienceDirect, SpringerLink, or institutional e-book repositories (e.g., Delnet or National Digital Library programs).
Varghese describes this text as a "panacea" because it bridges the gap between pure earth science and the challenging circumstances encountered in large-scale construction. Whether you're working on reservoirs, dams, tunnels, or high-rise foundations, understanding the lithosphere's properties is non-negotiable for safe design. Key Topics Covered
Chapter 15 contains a workflow diagram for tunnel alignment that is often missing in scanned copies. It instructs engineers to avoid crossing fault zones at an angle less than 45 degrees. Without this diagram, you might route a tunnel directly into a landslide-prone shear zone.
