Mechanical Response and Failure Mechanism of Rock Under Dynamic Disturbance and Water

The field of geotechnical engineering has long recognized the critical role of water-rock interactions in influencing the mechanical behavior of rock masses, particularly in the context of mining and civil engineering applications. Recent research has focused on the dynamic behavior of soft rocks in water-rich environments, which is crucial for the safe and sustainable extraction of coal and other minerals. Studies have employed various experimental setups, such as creep-impact dynamics and uniaxial compression tests, to investigate the mechanical properties and acoustic emission behaviors of both dry and water-saturated soft rocks. These experiments have revealed significant insights into the hysteresis loop behavior, the phases of strength and weakening under dynamic disturbances, and the classification of acoustic emission signals. However, despite these advancements, there remains a need to further understand the deformation and instability mechanisms in water-rich rock masses, as well as the influence of water content on rock strength, energy dissipation, and failure propensity under impact. The complex interplay between water saturation, fissure presence, and dynamic loading rates continues to pose challenges in predicting and mitigating geotechnical hazards such as water inrush and rockburst events.



This research topic aims to deepen our understanding of the dynamic responses of water-saturated soft rocks and other rock types under various loading conditions, and to elucidate the mechanisms driving their deformation, failure, and acoustic emission behaviors. By exploring the multi-scale effects of water-rock interactions, the goal is to develop more accurate predictive models and effective mitigation strategies for geotechnical hazards. The research will also investigate the impact of water content on the mechanical properties of rocks, the evolution of microcracks, and the degradation mechanisms under wetting-drying cycles, with a focus on improving the safety and efficiency of underground engineering projects.
