Limestone as one of the primary raw materials for concrete, which is mechanically crushed
into different sizes according to the grading requirements of aggregates, or is ground into …

The ultrasonic tensile test method recently developed by the Authors is applied with the
micro-computed tomography technique aiming to correlate the failure-inducing nominal …

In recent years, with the improvement of construction safety requirements in deep well
mining, the backfill mining method has been widely used. However, the strength of paste …

The pre-existing cracks with various geometric and physical properties significantly affect the
mechanical behaviors of rock mass. In this study, uniaxial compressive tests are performed …

Engineering rock containing flaws or defects under a large water source is frequently subject
to the couple influence of constant crack water pressure and geostress. To investigate the …

Tensile and shear failure are the main damage modes of rocks in geotechnical engineering.
To investigate the energy evolution and failure characteristics of coarse-grained sandstone …

As a special type of joint fracture, the fracture evolution characteristics of parallel double
joints have important engineering significance for the stability analysis of fractured rock …

In this work, the color difference phase separation (CDPS) approach is proposed to segment
the solid and pore phases. Pore‐scale variables are defined to describe the microstructural …

The Kaiser effect exhibits stress-induced changes in the acoustic properties of rock, so
accurately identifying the Kaiser point of rock under complex conditions is essential for …

The effect of earthquakes on deep tunnels near faults has always been a significant issue in
underground engineering research. The presence of fault fracture zones tends to intensify …
