Research on Failure Mechanism and Parameter Sensitivity of Zonal Disintegration in Deep Tunnel
With the increase of excavation depth, the zonal disintegration phenomenon appears in the deep rock mass, which is quite different from the failure mode of shallow tunnel. In order to analyse the failure mechanism of this phenomenon, an elastoplastic softening damage model was put forward based on t...
