The article presents the study results and gives the explairation on prestress condition of multi-layer lining in order to reinfbrce circular .rorr-r tiJn tunnels, which built in heterogeneous soils' In this study' the displacemont of tunnel multi-layer lining and soil massaround the tunnel are- united support system ,,multi-layer lining - soil mass" The supporiing jackets and.surrourding soil mass are considered as the only in aerormauL system of " multi-layer lining - soil mass"
Keywords:massif soil, technological heterogeneity, tunnel lining, stress, strain, elasticity theory'
