The failure mechanism and failure mode of anisotropic rock masses are very different from
those of isotropic rock masses. For unsupported tunnels, the failure modes of anisotropic …

Partial extraction methods such as underground strip pillar mining or room-and-pillar mining
are widely adopted techniques to control ground subsidence. However, pillar failure in …

Tunnel excavation inevitably causes variations in stress and displacement fields in soil,
which could affect the serviceability and safety of the adjacent underground structures …

It is of great significance for ensuring the lining safety to reasonably determine the earth
pressure on the tunnel, especially the deep-buried tunnel. In this study, the stress-transfer …

In this paper, the stability of an underground cavern group is investigated on the basis of
large-scale 3D geomechanical model tests and numerical simulations. Multiple …

This review summarizes the development of particle-based numerical manifold method
(PNMM) and its applications to rock dynamics. The fundamental principle of numerical …

Underground storage in unlined caverns is of great significance for storing energy
resources. Construction of underground storage caverns is an extremely complex process …

The islands and coasts in the South China Sea have developed coral reefs, which are the
basis for the development of ocean resources and the construction of ocean engineering …

Understanding the failure process and the load-bearing arch effect of the surrounding rock is
crucial for the stability control and support design of tunnels under high geostresses. In this …

The stability of high sidewalls of large-span underground openings is a crucial geological
engineering issue when the steeply inclined rock strata form a small angle to the cavern …
