Sprayed Concrete Lined Tunnels

Sprayed concrete lined (SCL) tunnels are gaining popularity due to their versatility, but their complex early age behavior makes design difficult. This book provides an excellent introduction to SCL tunnelling, covering all aspects from constituents to design and management. It also includes new sections on permanent sprayed concrete, waterproofing membranes, fiber reinforcement, and composite lining design. Sustainability and environmental impact are addressed.

Sprayed concrete lined (SCL) tunnels are gaining immense popularity due to their remarkable versatility. The advent of the SCL method has brought about a revolutionary transformation in the design and construction of both hard rock and soft ground tunnels. The utilization of permanent sprayed concrete linings has unlocked the full potential of the method, enabling it to significantly reduce construction costs and times. However, the complex early age behavior of sprayed concrete poses challenges in the design process and necessitates a robust management system during construction. It is crucial to balance the immense advantages of the SCL method against the associated risks, as evidenced by a few high-profile tunnel collapses.

This book serves as an excellent introduction for practicing engineers, whether they are on-site, in the design office, or within client organizations. It comprehensively covers all aspects of SCL tunneling, encompassing the fundamentals of sprayed concrete, detailed design considerations, and effective management strategies throughout the construction phase. While there is a close interdependence among the various facets of sprayed concrete, it is noteworthy that few engineers possess the requisite breadth of experience and expertise to cover all of them. This gap urgently needs to be addressed within the broader engineering community, as SCL tunnels play an increasingly significant role in delivering the underground infrastructure that modern urban life demands.

In the second edition of this book, beyond a general updating to reflect new developments, significant expansions have been made to the sections on permanent sprayed concrete, innovative technology of spray applied waterproofing membranes, fiber reinforcement (both steel and macrosynthetic), and composite lining design. Sustainability and environmental impact have been addressed in a dedicated section, recognizing the importance of these factors in the construction industry.

By providing a comprehensive and up-to-date resource, this book aims to equip engineers with the knowledge and skills necessary to excel in the field of SCL tunneling. It serves as a valuable tool for professionals seeking to enhance their understanding and expertise in this rapidly evolving area of infrastructure development.
