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...
