Influence Of Shield Tunneling On Adjacent Structures And Control Technology

This book introduces the synergy theory model to analyze the calculation results of the soil deformation and the lateral displacement law caused by the longitudinal shield tunneling based on in-depth scientific research and engineering practice on deformation of structures caused by shield tunneling. The influence of shield tunneling on different adjacent foundation buildings was studied, and the deformation law and internal force distribution law of the structures were obtained. It aims to help practitioners in understanding the mechanism, predictive analysis method, and corresponding control technology of the influence of surrounding structures’ deformation caused by shield tunneling.

Shield Tunnel Engineering: From Theory to Practice is a key technique that offers one of the most important ways to build tunnels in fast, relatively safe, and ecologically friendly ways. The book presents state-of-the-art solutions for engineers working within the field of shield tunnelling technology for railways. It includes expertise from major projects in shield tunnel construction for high-speed rail, subways and other major projects. In particular, it presents a series of advances in shield muck conditioning technology, slurry treatment, backfill grouting, and environmental impact and control. In this volume, foundational knowledge is combined with the latest advances in shield tunnel engineering. Twelve chapters cover key areas including geological investigation, the types, structures and workings of shield machines, selecting a machine, shield segment design, shield tunnelling parameter control, soil conditioning for earth pressure balance (EPB) shield tunnelling, shield slurry treatment, backfill grouting, environmental impact, and problems in shield tunnel structures and their amelioration. This book presents the essential knowledge needed for shield tunnel engineering, the latest advances in the field, and practical guidance for engineers. Presents the foundational concepts of shield tunnel engineering Gives the latest advances in shield tunnel engineering techniques Considers common problems in shield tunnel structures and their solutions Lays out step-by-step guidance for engineers working with shield tunnelling Assesses environmental impacts and their control in shield tunnel engineering

This book systematically introduces the new technology used in the construction of underwater large slurry shields under complex conditions. The basic principles, scope of application, construction technology and technical points of the key technologies such as the origin and arrival of the shield, crossing the shallow soil in the middle of the river, crossing the guard, and changing the knife and opening the knife are clarified.

Internationally, the mechanized excavation of tunnels has intensified in the last two decades, as the number of tunnels being constructed for subways and railway underpasses increases. The subject of mechanized tunnelling in urban areas has not previously received the attention that it deserves, despite there being specific hazards associated with the construction of tunnels in metropolitan areas, including poor ground conditions, water tables higher than the level of tunnels, and subsidence leading to damage to the existing structures on the surface. The application of technologies for achieving the stability of the tunnel and for minimizing surface settlement is described in this book. Accurate characterization of the ground; rigorous assessment and management of risk from design to maintenance; the correct choice of a tunnel boring machine and a plan for the advancement of the tunnel; specific excavation procedures and real-time monitoring of excavation parameters are all discussed in this thorough work.
