Investigation on deformation behavior of unstable rock belt based on multi-source data analysis
Slope failure triggered by collaboration of coal-mining activities, structural plane, karstification and rainfall is very frequently occurred in Guizhou, China. Subsequent four rock topples occurred in Daxian village, Bijie City since October 2022 continuously threatening the safety of the residents and exhibited a high possibility of reoccurring geohazards in the Yiziyan unstable rock belt. Temporal and spatial multi-source data from GNSS, sensors, video footage, aerial image and remote sensing are integrated to reveal the unstable rock belt deformation behavior. Detailed macro- and microscopic data reveal that slope experienced a three-stage deformation process with different displacement rate since devices started to monitor. Based on the comprehensive monitoring data, inverse-velocity method (IVM) was improved with two quantitative indexes: displaced angle and crack width, and it indicated a slope failure event approximately on 23rd June 2023. According to the prediction result, government emergently evacuated all the residents and took effective disaster management. Therefore, fatalities were avoided in the major rock topple event occurred on 20th June 2023 in Yiziyan which served as a highly valuable case of successfully forecast approaching slope failure. The modified IVM provides specific precursor of future potential geohazards in the similar geological condition in Guizhou.
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.
