The shallow tunnelling method (STM) is usually used to construct tunnels buried in soft ground. It consists of primary lining and secondary (tunnel). In the seismic design STM tunnels, it assumed that (tunnel) resistant all effects. However, soil–primary–secondary system may generate complex interaction phenomena during ground shaking. Compared with case where not considered, existence alters r...

Affected by dip angle and thickness of strata the tunneling method, soft rock tunnel has obvious characteristics large deformation, long deformation time difficult support. Based on a case study Gelong failure mechanism surrounding rock, stress supporting structural control method section highway passing through strong-medium weathered carbonaceous slate stratum are studied. This paper proposed...

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...

According to construction scheme of some weak surrounding rock large span double and multi-arch tunnel works, finite element value simulation method is adopted to research weak surrounding rock deformation characteristic, anchor bolt mechanics characteristic, preliminary support and secondary lining structure mechanical characteristics, etc, and the research result shows that: repeatedly distur...
