Tunneling in urban areas has grown considerably in recent decades, with increasingly ambitious projects. One of the major challenges for engineers is to ensure both safety during the construction work and its surrounding in an increasingly complex context. Engineers seek to improve their calculation models of the underground structure, beyond the three-dimensional and highly non-linear aspects, most take into account the behavior of the support structure elements, which mainly consist of segments forming the ring of the tunnels by mechanical assembly within them. In certain cases, knowing the detailed behavior of the joints connecting the segments is essential, as it can substantially influence the calculation methods.The framework of this thesis is in line with the objective of better understanding and proposing improvements to the calculation tools for tunnel lining with segmental rings.The first objective of this work is to evaluate the reliability of existing approaches in the current literature with regards to the influence of joints in the tunnel structure. The second objective is to propose practical numerical modeling for the joint with a behavioral law that takes into account all the non-linearities of the material and geometrical parameters that influence the joint behavior.A comparative numerical study of the existing methods is done and introduced in the literature review. Based on the data gathered from the study, it has been noted that the different methods generally work well, but on condition that they can be calibrated to data which is sometimes unavailable. Therefore, a limitation of the existing methods is observed, hence the need to describe the joint behavior in the most relevant way according to geometry and joint characteristics.The second objective is to propose a three-dimensional finite element model capable of taking into account the complex local behavior of the joints through a global approach, based on four-point bending tests of two segments and a longitudinal joint. A parametric study has been done on this model to study the influence of parameters related to material non-linearities and interface geometry on the joint behavior. A non-linear longitudinal joint behavior law (Moment versus rotation) is proposed and validated with experimental tests. The calculations are also extended to the non-linear behavior of concrete, taking into account the plasticity and damage on the concrete.The last part aims at providing a practical approach to model the longitudinal joint macro-element by one-dimensional finite element. This simplified method takes into account the complex local behavior, including the non-linearities of the material and geometrical parameters that influence the joint behavior (number of bolts, the thickness of the segment, loading, damage and joint resistance...) through a global approach. The reliability of the proposed model was confirmed by good correspondence between the simulation results experimental tests

The National Agency for Radioactive Waste Management (FR Andra) in France suggested a new way to design a tunnel lining, especially, beneficial in the case of very deep tunnels. To avoid very thick tunnel segments, they propose to integrate a layer of granular material on the extrados of the thinner lining. This approach takes the advantages of the compressible capacity of the crushable particles and the load transfer in the granular material. A tunnel segment with such design is called a Mono-block Compressible Arch-segment VMC (Andra’s & CMC’s pending patent) and is an innovative new type of tunnel linings.This PhD dissertation is dedicated to the creation of a numerical model capable of reproducing the mechanical behaviour of this compressible granular layer using 3D Discrete Element Method (DEM). The granular packing is made of the brittle hollow coarse-size cylindrical particles, called shells. Each shell is a 2 cm long tube with a diameter of 2 cm. Its small thickness makes the cylindrical shell mainly made of void surrounded by a thin layer of clay. In the model, a breakable cluster (shell) is generated using sphero-polyhedral elongated clumps. These clumps, called sectors, are glued together using two adhesive contact force laws. If the combination of the normal and tangential contact forces exceeds a suitable failure criterion, a de-clustering of the shell (breakage) occurs. The DEM tool Rockable devel- oped for this research can operate on such crushable particles. The mechanical properties of the shell model, composed of 12 to 24 sectors, are adjusted in the case of a uniaxial (vertical) radial compres- sion of shells. The preceding grain-scale experiments on the true shells made of baked clay serve as a reference. We determine the true range of the failure tensile load and its statistical Weibull distribu- tion. The user-specified parameters is then successfully validated in the case of radial compression of a horizontally constrained shell.Firstly, the macroscopic study of shell assemblies focuses on the experimental characterisation of the samples with a control of the initial state variables like a number density and a spatial arrangement of shells (shells orientations). 3D reconstruction from X-ray tomographies of the original coated shells samples extracted from the extrados of a tunnel segment help us to characterise the anisotropy of the shells orientation. This is a piece of valuable information to the generation the numerical samples of shells with relevant initial features. Secondly, a series of DEM oedometric tests on ⟨1 000 : 2 000⟩ shells is simulated. A parametric study successfully leads to the understanding of each internal state variable role. A well-chosen set of initial variables with properly adapted DEM parameters give the relevant predictive simulations for a final comparison with the experimental oedometer tests. Thanks to a discrete insight into the micromechanics, the evolutions of the breakage level, the orientation anisotropy and the local stresses exerted on the shells (and/or the fragments) are quantified during the compression. The breakage of the shells result in high compressibility of the material. Therefore, the mechanical response is seen as a consequence of the breakage evolution. Finally, an analytical model is suggested in order to predict the Stress↔Void ratio relationship knowing the initial state of the sample and the tensile strength of the constituents: the shells
