Analysis of load formation on lining of tunnel constructed in soil with nonlinear behavior

Article preview

Method  of excavation support and tunnel lining design is worked  out. Stiffness of soil strata is considered as nonlinear elastic. The problem is solved in plane strain condition according to elastic theory. The distribution of average load on excavation support is given.

PRediction of spatial stress-strain double-track tunnels Frunzensky radius Saint Petersburg underground

Article preview

In this article the analysis of the stress-strain state of the external and internal contours of the lining, which appears during the process of the drilling of tunnels with using of contledge of the face which applied in Tunnel Boring Machines, is adduced. The finite element method diagrams obtained the minimum and maximum principal stresses on the outer and inner contours of output. Relationship obtained in the surface sediments depending on the depth of the tunnels.

Prediction of spatial stress-strain soil mass state tunneling technology with kentledge оf the working face

Article preview

In this article the analysis of reinforcing effect, which appears during the process of the drilling of tunnels with using of contledge of the face which applied in Tunnel Boring Machines (TBM), is adduced. By applying of the finite-elements method the family of graphical relations, which  reflects the processes of the development of displacements, is approached. The influence  of the main strength characteristics of Couloumb-Mohrs’s theory of strength on  stability of the face of the tunnel and the necessary value of contledge of the tunnel’s face are defined.
