Available in PDF, EPUB and Kindle. Book excerpt: This book presents the theoretical bases and the application tools for using the 'convergence-confinement' method which is a rational method largely used in design engineering for tunneling. Until recently, the stability conditions of underground works and the choice of support methods were essentially defined on the basis of good practice or empirical methods. The progress made, on one hand on the knowledge of the constitutive laws of soils and rocks and, on the other hand on the numerical modeling of the interaction between the ground and the structures have led to the development of robust design tools for tunnels supports. The convergence-confinement method makes it possible to simulate the excavation of a tunnel and the installation of the support using a simple plane strain model. The book presents the theoretical bases of the method and its most recent developments. Closed-form solutions for stress and displacement fields around tunnels are provided for elastic, viscoelastic and elasto-plastic behavior of the ground. More generally, the principles for applying the method in numerical models are presented.

Available in PDF, EPUB and Kindle. Book excerpt: This work illustrates how the Analysis of Controlled Deformation in Rocks and Soils (ADECO-RS) is used in the design and the construction of tunnels. This is a very new and effective way of tunnel construction. The ADECO-RS approach makes a clear distinction between the design and the construction stages and allows reliable forecasts of construction times and costs to be made. It uses the advance core (the core of ground ahead of the face) as a structural tool for the long and short term stabilisation of tunnels, after its rigidity has first been regulated using conservation techniques.

This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on a large-diameter and shallow-depth tunnel project for passenger cars and rail trains. Monitoring equipment (string gauge, ground settlement points, etc.) were installed from the outset of the project to gather pertinent data. With this large data set, used to monitor and analyze the surrounding soil and support structure of the tunnel, Convergence-Confinement Method (CCM) was systematically developed, including the Support Confinement Curve (SCC), Ground Reaction Curve (GRC), and Longitudinal Displacement Profile (LDP). First, this research initially aimed to identify the optimal approach for constructing these three CCM graphs: For SCC, the spatial distribution of axial force, bending moment, and radial displacement within the tunnel structure will be illustrated and compared with the other two models. Subsequently, essential field data will be utilized to establish the SCC. The GRC was formulated using a hardening soil model, selected after comparing indoor soil tests across various models. LDP were derived from monitoring the embankment's settlement as the tunnel was constructed. A numerical model was constructed and verified using monitoring results. This includes presenting and comparing the cross-section settlement curve with Peck's findings. Through these methods, the study sought to establish best practices for generating these key CCM graphs. The second thrust of this dissertation assembles these three curves and verification CCM from the construction process in a real large-diameter and shallow-depth tunnel project, validating the CCM equilibrium stress against monitoring data and corroborating the CCM results with data from strain gauge monitoring underscore the methodology's validity and reliability, establishing guidelines for tunnel project designs. Finally, to assess the applicability of CCM, the various findings resulting from this research are presented. This study finds that Terzaghi in-situ earth pressure is closer to CCM equilibrium earth pressure, which represents the soil stress after release. Therefore, Terzaghi loose earth pressure is deemed more suitable for application in the design in the Yellow River area. This study also extends to Wood's work to derive the compression factor when the tunnel is in the 'elliptical' mode of deformation and subsequently determined stress and displacement fields around a supported tunnel.

Book excerpt: Tunnel Design Methods covers analytical, numerical, and empirical methods for the design of tunnels in soil and in rock. The material is intended for design engineers looking for detailed methods, for graduate students who are interested in tunnelling, and for researchers working on various aspects of ground-support interaction under static and seismic loading. The book is divided into seven chapters, covering fundamental concepts on ground and support behavior and on ground-excavation-support interaction and provides detailed information on analytical and numerical methods used for the design of tunnels, with applications, and on the latest developments on empirical methods. The principles and formulations included are used, throughout the book, to provide insight into the response of tunnels under both simple and complex loading conditions, thus providing the reader with fundamental understanding of tunnel behavior. Both authors have experience in tunnelling and have worked extensively in practice, designing tunnels both in the United States and abroad, and in research.

Available in PDF, EPUB and Kindle. Book excerpt: Tunnel construction is expensive when compared to the construction of other engineering structures. As such, there is always the need to develop more sophisticated and effective methods of construction. There are many long and large tunnels with various purposes in the world, especially for highways, railways, water conveyance, and energy production. Tunnels can be designed effectively by means of two and three-dimensional numerical models. Ground–structure interaction is one of the significant factors acting on economic and safe design. This book presents recent data on tunnel engineering to improve the theory and practice of the construction of underground structures. It provides an overview of tunneling technology and includes chapters that address analytical and numerical methods for rock load estimation and design support systems and advances in measurement systems for underground structures. The book discusses the empirical, analytical, and numerical methods of tunneling practice worldwide.

Book excerpt: The classic work on the evaluation of city form. What does the city's form actually mean to the people who live there? What can the city planner do to make the city's image more vivid and memorable to the city dweller? To answer these questions, Mr. Lynch, supported by studies of Los Angeles, Boston, and Jersey City, formulates a new criterion—imageability—and shows its potential value as a guide for the building and rebuilding of cities. The wide scope of this study leads to an original and vital method for the evaluation of city form. The architect, the planner, and certainly the city dweller will all want to read this book.
