A simplified analytical solution for steel plate strengthened circular tunnel concrete linings is presented, considering various interface slip modes. The full derivation the introduced in detail, from which explicit expressions stress and displacement fields throughout system are obtained. distribution of lining deformation, internal force, interaction between were investigated by tunnel-steel...

In this paper, artificial neural network (ANN) models are presented in order to enable a prompt assessment of the stability factor tunnels rock masses based on Hoek–Brown (HB) failure criterion. Importantly, safety is one serious concerns for constructing and requires reliable accurate analysis. However, it challenging engineers construct finite element limit analysis (FELA) algorithms with HB ...

The numerical prediction of vibration in buildings due to underground railways involves modelling many physical phenomena. Not least these is the dynamic soil-structure interaction that exists between various elements system. majority existing models assume railway tunnel and building’s foundation negligible, with two sub-systems behaving as though they are uncoupled. This paper presents some i...

Abstract Segmental lining is subject to significant upward buoyancy forces when a grouting material (slurry), initially fluid, adopted fill the gap between its external profile and wall of tunnel excavated with TBM machine. The analysis effects these important in order correctly dimension segmental avoid damage subsequent costly maintenance restoration actions. Given complexity behavior consist...

There are many underground tunnels of various shapes located in seismically active areas that need to be protected from seismic impacts. The paper considers the impact harmonic waves on a cylindrical shell viscoelastic half-plane. study's main purpose is determine stress-strain state when exposed waves. basic equation viscoelasticity displacements with corresponding boundary conditions obtained...

A low-clearance tunnel portal in the shallow-buried, joint-developed, broken, and loose surrounding rock slope deposit may cause safety issues during construction. In this study, Guanyin Mountain Tunnel of Chong-Ai expressway was taken as a case characteristics broken rocks, their low clearance, shallow buried bias were comprehensively studied. The three-dimensional numerical model section cons...
