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.

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 volume presents a selection of chapters covering a wide range of tunneling engineering topics. The scope was to present reviews of established methods and new approaches in construction practice and in digital technology tools like building information modeling. The book is divided in four sections dealing with geological aspects of tunneling, analysis and design, new challenges in tunnel construction, and tunneling in the digital era. Topics from site investigation and rock mass failure mechanisms, analysis and design approaches, and innovations in tunnel construction through digital tools are covered in 10 chapters. The references provided will be useful for further reading.

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.

Practising engineers on site, in the design office or in client organizations will find this book an excellent introduction to the design and construction of sprayed concrete lined (SCL) tunnels. The complex behaviour of the early age behaviour of the sprayed concrete requires careful management. This book covers all aspects of SCL tunnelling – from the constituents of sprayed concrete to detailed design and management during construction. Although there is a close interdependence between all the facets of sprayed concrete, few engineers have the right breadth of experience and expertise, and this urgently needs to be transferred to the wider engineering community. Disseminating essential information for tunnelling engineers, Sprayed Concrete Lined Tunnels is key reading for all involved in or studying the process.
