TBMs were analyzed in 2D models. Panet (1988) and Benmebarek et al. (1998) used concepts of stress release and volume loss, respectively, at each stage of the underground work. However, these approaches require the use of empirical coefficients such as the deconfinement ratio to take into account the three-dimensional effect. To assess the impact of the shield tunneling key components on ground movements, only a three-dimensional approach that takes into account each of them can directly reproduce the physics of the problem. In the recent years, 3D models become

thereof, and couplings of different models in different subregions. The techniques that we will employ in the first part of the article ( Sections 3 through 7 ) are those of Laplace transforms, understanding the influence of volume forces, normal stresses, and given displacements, as well as the strain-stress relation as transfer functions describing linear distributional processes in the time domain. These techniques are classical, although we will use them in a language that is borrowed from the recent literature of time domain integral equations. In a second part
