Description

This book provides a comprehensive and technically grounded exploration of modern mechanised tunnelling, with a focus on the principles, systems, and operational practices that underpin Tunnel Boring Machine (TBM) technology. Tunnel Boring Fundamentals bridges the gap between engineering theory and real-world application, guiding readers through the full lifecycle of tunnel construction—from ground behaviour and stress redistribution to machine design, excavation mechanics, and project delivery.

Recognising tunnelling as a multidisciplinary field, the text integrates geotechnical engineering, structural design, mechanical systems, and construction management within the context of uncertain and variable subsurface conditions. It begins with core concepts such as tunnel geometry, ground–structure interaction, and geological variability, before progressing into detailed analysis of TBM types, components, and cutting processes. Readers gain insight into how machines interact with soil and rock, as well as how tunnelling operations are planned and executed.

The book examines all stages of the tunnelling process, including site setup, machine launch, advance control, segmental lining installation, spoil removal, and performance optimisation. A strong emphasis is placed on engineering calculations, enabling readers to quantify key parameters such as thrust, torque, penetration rates, face pressure, and lining loads. Practical guidance is also provided on ground conditioning, survey control, safety, and maintenance.

Emerging technologies are explored in depth, including automation, predictive maintenance, real-time monitoring, and digital twins, highlighting the shift toward intelligent, data-driven tunnelling systems. Supported by real-world case studies, the book demonstrates how theory is applied in practice.

Designed for students and professionals, this text serves as both a foundational reference and an advanced guide to modern tunnelling engineering.
