Rock engineering is highly susceptible to cyclic loads resulting from earthquakes, quarrying
or rockbursts. Acquiring the fatigue properties and failure mechanism of rocks is pivotal for …

Suitable numerical models of masonry structures are very important in their response
evaluation under various loading events. Masonry is a heterogeneous material, made of …

The dynamic mechanical properties and failure characteristics of jointed rocks are the focus
of research in rock engineering. In this study, cement mortar specimens with 0–4 parallel …

Strength, deformability and failure behaviors of rock masses are significantly affected by the
widespread natural fissures that are often distributed in overlapped patterns. To investigate …

We conducted laboratory direct shear tests on two parallel coplanar intermittently jointed
rock to investigate the effect of joint roughness and loading conditions on the shear behavior …

Joint roughness coefficient (JRC) is the most commonly used parameter for quantifying
surface roughness of rock discontinuities in practice. The system composed of multiple …

To investigate the macro-meso cumulative damage mechanism of the discontinuities in soft-
hard interbedded rock mass, laboratory pre-peak cyclic shear tests and PFC 2D meso …

The shear strength deterioration of bedding planes between different rock types induced by
cyclic loading is vital to reasonably evaluate the stability of soft and hard interbedded …

Fault stability evaluation is crucial for ensuring safety of underground gas storage (UGS)
reconstructed from depleted oil and gas reservoirs. To make assessment result more …

To promote the understanding of the shear behavior of intermittent joints subjected to cyclic
shear loads, this paper provides the experimental results of cyclic shear tests in the …
