To investigate the asymmetric failure mechanism and failure mode of layered rock tunnels, a
novel mixed-mode power exponent cohesive zone model (M-PECZM) is proposed in this …

A Voronoi-element based explicit numerical manifold method is adopted to investigate the
evolution process and failure characteristics of the excavation damaged zone around a …

The proper assessment of stability of overburden (OB) dump slopes for the prevention of
unforeseeable incidents has become a crucial issue for the coal mine industries across the …

The present study attempts to examine the behavior of circular tunnel excavation in rock
mass under anisotropic stress conditions with various postpeak behaviors. A brief review of …

The entire Himalayan arc is predicted to produce a series of significant earthquakes and the
subsequent great earthquakes of magnitude 8.0 and higher. A substantial amount of rock …

Given the single and one-sided problems of traditional rock mass structure integrity
evaluation methods, this paper will use borehole test data that were obtained by …

Tunnel excavation has always been an important reason for the stability failure of the tunnel‐
slope system at the portal section. In case of rainfall, it is likely to cause serious disasters …

Recent cases of damage to mountain tunnels have raised concerns about the seismic
performance of underground structures. The damaged sections have been majorly observed …

In this paper, to study the stability of surrounding rock during roadway excavation in different
rock mass structures, the physical model test for roadway excavation process in three types …

A novel formulation has been developed for allowable bearing capacity of partially saturated
geomaterial considering the strength nonlinearity for a steady-state surface flux boundary …
