Abstract
A crucial deformation phenomenon is observed in shale and silty clay sections in a tunnel. To analyse the reinforcement and support mechanism and behaviour of the tunnel support structure in layered soft rocks, field tests for the axial force of the cartridge rock bolt, surrounding rock pressure, stress of a steel I-beam and lattice girder were performed. Based on the field deformation analysis data, the reinforcement behaviours of the cartridge rock bolt and steel floral pipe, and support behaviours of lattice girder and steel I-beam in the layered rock mass and silty clay were analysed.
