With the shallow resources dwindling, many countries have entered into deep mining one
after another. Rock fracture caused by high stress mining disturbances is a significant …

After the excavation of deep underground engineering, the complex 3D high-stress
redistribution occurs in the surrounding rock, resulting in deterioration of mechanical …

Deep rocks are typically under a true-triaxial stress state. The strength of deep rock is thus
dictated by both the direction and magnitude of principal stresses. The formulation of three …

Obtaining a reasonable assessment of the stability of high-level pillars stabilized using
cemented backfill is particularly important when designing deeply-buried metal mines. This …

The surrounding rock in deep underground engineering is often subjected to true three-
dimensional high-stress conditions. Excavation unloading results in changes in the stress …

After the excavation of deep underground engineering, the three-dimensional (3D) stress
state redistributes, leading to a significant change in the mechanical properties of the …

Mechanical excavation, blasting, adjacent rockburst and fracture slip that occur during
mining excavation impose dynamic loads on the rock mass, leading to further fracture of …

Rock serves as a crucial source of building materials. Understanding the dynamic strength
of rock under varying prestressed conditions is essential for evaluating structural stability …

To investigate the effects of the maximum principal stress direction (θ) and cross-section
shape on the failure characteristics of sandstone, true-triaxial compression experiments …

To study the spalling characteristics and induction mechanism of tunnels with different arch
structures, a series of true triaxial tests were conducted on three types of cubic granite …
