Crack development initiated from nonpersistent joints in rock mass plays a key role in the
instability of rock structures. In particular, the dynamic behavior of nonpersistent …

In the process of underground construction, it is common to spray concrete on the working
surface, which will form a concrete-rock composite structure, to achieve the expected …

Weak-filling joints substantially degrade the integrity and load-bearing capacity of rock
masses, thus increasing the complexity and unpredictability of their mechanical response …

Failure patterns of rock specimens represent valuable information about the mechanical
properties and crack evolution mechanism of rock. Several kinds of research have been …

This work aims to investigate the influence of cavity diameter on fracture behaviors for
fissure‐contained hollow‐cylinder granite subjected to multistage cyclic loads, using …

The stability control of fissured rock is difficult, especially under static and dynamic loads in
deep coal mines. In this paper, the dynamic mechanical properties, strain rate evolution and …

This study aims to make a unique contribution to the existing body of knowledge about rock
strength and deformation parameters and crack stress thresholds through intelligent and …

The impact of weak filling joints with multiple angles on the energy dissipation mechanism is
significant for surrounding rock engineering to prevent and mitigate disasters. In the present …

Mortar-rock composite structures are very common in underground engineering. Their
mechanical behaviour and failure modes are much more complicated than those of pure …

The strength of jointed rock mass is significantly affected by discontinuities. In particular, the
impact of non-persistent joints on the strength of rock mass needs to be investigated further …
