Abstract

The analysis of soils stress-strain condition for different lining including in work period retards from tunnel’s face with applying of finite-elements method is adduced. The graphical relations of stresses, displacements, soils inelastic area configuration were obtained. According to these relations final graphical relation of temporary grouting influence for permanent lining stress-strain condition was  developed.
