We present a discussion of the state-of-the-art on the use of discrete fracture networks
(DFNs) for modelling geometrical characteristics, geomechanical evolution and …

A coupled thermal-hydro-mechanical (THM) model based on the combined finite-discrete
element method (FDEM) is presented for simulating rock cracking driven by multi-physics …

Numerical back analysis is a valuable tool available to rock mechanics researchers and
practitioners. Recent studies related to back analysis methods focused primarily on …

In underground space engineering, the humidity in the environment has a great influence on
the structural performance of soft rock roadway. It not only changes the stress state of rock …

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 …

During the construction of an underground excavation, damage occurs in the surrounding
rock mass due in large part to stress changes. While the predicted damage extent impacts …

Large deformation is a crucial factor in deep-buried tunnels constructed through soft rocks
with a high geostress. Taking the deep-buried Baozhen tunnel through layered shale as an …

This paper presents a new, fully-coupled, hydro-mechanical (HM) formulation for a finite-
discrete element method computer code. In the newly-developed, hydraulic solver, fluid flow …

This study focuses on rock damage potentially developing in the near-field of a planned
underground nuclear waste repository at the Forsmark site (Sweden). In hard, crystalline …

The sequential excavation method (SEM), in which the tunnel face is partitioned into several
temporary drifts, can promote face stability and reduce ground displacement. Three-bench …
