Effect of the Initial Support of the Tunnel on the Characteristics of Rockburst: Case Study and Mechanism Analysis

open access: yesAdvances in Civil Engineering, 2022
Rockburst is still a stubborn disease in the field of engineering geology. The present research pays more attention to the influence of geological conditions on rockburst and less to the influence of type and stiffness of engineering support on rockburst.

Study on Catastrophe Information Characteristics of Strain-Structural Plane Slip Rockburst in Deep Tunnels

open access: yesApplied Sciences, 2023
Rigid structural planes encountered during construction have an obvious influence on rockburst intensity and occurrence mechanism. The high-intensity rockburst induced by the structural plane poses a great threat to the safety construction of the tunnel.

A New Theoretical View of Rockburst and Its Engineering Application

open access: yesAdvances in Civil Engineering, 2018
Traditionally, rockburst is considered as a dynamic phenomenon of sudden destruction of coal/rock mass. In this study, rockburst is treated as an event process rather than a phenomenon. This paper introduces typical rockburst process, its classification,
