Influence of bedding angle on rockburst behavior of sandstone: insights from energy storage and dissipation
Understanding the rockburst behavior of layered rocks is of great significance for ensuring the safety of underground engineering and optimizing design and construction. To explore the influence of bedding angle on the rockburst behavior, uniaxial compression tests with single unloading were conducted on layered sandstone, separating elastic energy and dissipated energy by unloading and obtaining energy distribution characteristics at different loading stages. The laboratory results indicate that the distribution relationship between elastic and dissipated energy follows the linear energy storage and dissipation (LESD) law. As the bedding angle increases from 0 to 90°, the elastic energy conversion coefficient varies from 0.7296 to 0.7722, and peak elastic energy decreases from 295.74 mJ/cm3 to 201.24 mJ/cm3, indicating that the bedding angle has little effect on the elastic energy conversion capacity but has a significant weakening effect on the peak energy storage capacity (mainly concentrated between 22.5° and 67.5°). Based on the LESD law, three energy-related indexes were calculated to evaluate rockburst proneness. Compared with the rockburst proneness index related to elastic energy conversion ability, the index related to peak energy storage capacity can better distinguish the influence of bedding angle on rockburst proneness, the rockburst proneness is greater between 0° and 22.5°. This study can help to better understand the influence of bedding angle on rockburst behavior from an energy perspective.
期刊介绍：
Engineering geology is defined in the statutes of the IAEG as the science devoted to the investigation, study and solution of engineering and environmental problems which may arise as the result of the interaction between geology and the works or activities of man, as well as of the prediction of and development of measures for the prevention or remediation of geological hazards. Engineering geology embraces:
• the applications/implications of the geomorphology, structural geology, and hydrogeological conditions of geological formations;
• the characterisation of the mineralogical, physico-geomechanical, chemical and hydraulic properties of all earth materials involved in construction, resource recovery and environmental change;
• the assessment of the mechanical and hydrological behaviour of soil and rock masses;
• the prediction of changes to the above properties with time;
• the determination of the parameters to be considered in the stability analysis of engineering works and earth masses.
