Description	This chapter introduces the methodology of the design process, its guiding principles and the design methods currently in use in tunnel engineering. The engineer's professional activity culminates in design, the word that comes from the Latin designare. The result of uniaxial compressive tests enabled definition of the advance length during the tunnel construction, which was associated with the surface displacements of the ground. The tunnel characteristic curve is defined as the locus of infinite balance states that can be achieved by limiting the natural radial pressure relaxation when the support elements are placed after the excavation. The stress–strain analysis approach is based on the deployment of approximate numerical calculation methods, which allow symmetries of any kind and little geometrical constraints. Upon completion of the ground characterization phase, the tunnel geomechanical profile is obtained which will be divided into ground segments having similar stress–strain properties. Book Name: Ground Characterization and Structural Analyses for Tunnel Design
