Working Face Stability of Box Shield Tunneling under Non-Uniform Support Pressure

Working Face Stability of Box Shield Tunneling under Non-Uniform Support Pressure

This paper proposes a theoretical model for the stability analysis of a box tunnel face in non-cohesive soils considering the uneven distribution of support pressure caused by multiple cutter heads and screw conveyors. The support pressure distribution on the tunnel face is concave. Accordingly, the...
