The existence of defects in a rock mass is a vital factor complicating the mechanical
response of the rock mass under stress. The characteristics of defects control the rock …

The deep surrounding rock is usually in the true triaxial stress state, and previous
constitutive models based on the understanding of uniaxial and conventional triaxial test …

This study investigated the sidewall rockburst characteristics of highly stressed circular
tunnel subjected to impact loads resulting from rock blasting or other mining-related dynamic …

Brittle failure, a common mode failure of hard brittle rock masses in deep excavation, is
intimately linked to the three-dimensional in-situ stress state. A comprehensive methodology …

Filling-type defects have a non-negligible effect on the propagation of explosive stress
waves in rock. Combined with the new dynamic caustics experimental system and …

Abstract The Gaoloushan Tunnel in Longnan City, Gansu Province, China, frequently
experiences rockburst disasters due to high in-situ stress. Managing rockburst in deep …

Rockburst prevention is an urgent task in deep-rock engineering, as support systems alone
are often insufficient for resisting high geostresses. Cutting slots in surrounding rock can …

This paper uses the displacement discontinuity method, one of the boundary element
methods, to solve two major engineering problems. The first one addresses the safe design …

The stability of inclined shaft lining structure (ISLS) in complex water-rich strata is affected by
many factors, such as water pressure, joint, soft rock, lining corrosion and so on. The …
