Shield Construction Techniques in Tunnelling is a comprehensive guide to this rapidly evolving, environmentally sustainable, and relatively safe construction technique. It delves into the technical risks and challenges encountered in China, highlighting the latest advancements and best practices in shield tunneling. The book begins by introducing the various types of shields used in tunneling, including segmental, continuous, and hybrid shields. It traces the historical development of the technique and discusses the fundamental principles of shielding. Selection, management, and the latest techniques in operation are explored in detail, along with engineering cases that showcase the practical application of shield tunneling. Construction in gravel, soft-soil, composite, and rock strata is discussed, along with the use of specialized equipment and techniques.

To enhance the learning experience, the book includes video clips of actual shield tunneling construction that can be accessed using QR codes embedded within the text. These videos provide a visual glimpse into the intricate processes involved in shield tunneling, allowing readers to gain a deeper understanding of the equipment and techniques employed.

The book combines theoretical knowledge with practical experience, providing readers with unique insights into shield equipment and construction techniques. It serves as a valuable resource for engineers, project managers, and researchers involved in tunneling projects, particularly in geologically complex areas.

Shield tunneling has gained widespread popularity, particularly in China, where it is being utilized to build urban-rail transit systems at an unprecedented scale and speed. The use of tunneling shields offers a fast, relatively safe, and ecologically friendly method for constructing tunnels, overcoming the limitations of traditional excavation methods. However, it is important to acknowledge that tunnelling through geologically complex areas poses significant risks.

Several incidents have highlighted the challenges associated with shield tunneling in such environments. One notable incident occurred in 2004 in Shanghai, where a shield tunneling machine encountered geological complexities and collapsed, resulting in the deaths of 21 workers. This incident underscored the importance of proper risk assessment, design, and construction management in shield tunneling projects.

To mitigate these risks, China has implemented strict regulations and guidelines for shield tunneling projects. These regulations cover aspects such as geological investigation, design, construction management, and emergency response plans. Additionally, advanced technologies and equipment are being developed to enhance the safety and efficiency of shield tunneling in complex geological conditions.

One of the key advancements in shield tunneling technology is the use of intelligent tunneling systems. These systems utilize sensors, cameras, and other advanced technologies to monitor the tunneling process in real-time and detect any potential hazards or abnormalities. This allows for timely intervention and prevents accidents from occurring.

Another important development is the use of pre-fabricated shield segments. These segments are manufactured in a controlled environment and can be transported to the construction site, reducing the time and cost of construction. Pre-fabricated segments also ensure a higher level of quality control and reduce the risk of defects in the final product.

In conclusion, Shield Construction Techniques in Tunnelling provides a comprehensive and up-to-date overview of the shield tunneling technique. It delves into the technical risks and challenges encountered in China, highlighting the latest advancements and best practices in shield tunneling. The book combines theory and practical experience, providing readers with unique insights into shield equipment and construction techniques. With the increasing demand for sustainable and efficient tunneling solutions, shield tunneling is poised to play a significant role in the future of infrastructure development.
