Abstract

Rainfall and groundwater level fluctuation lead to frequent rock slope instability accidents. In order to analyze the influence of rock mass saturation on rock slope, the relationship between saturation and uniaxial compressive strength is introduced into the shear strength of rock mass. A kinematic LA method is proposed to analyze the three-dimensional (3D) stability of rock slopes under different rock mass saturations. A hybrid optimization method is simultaneously employed to find the critical solution of the stability factor and the critical failure surface. The proposed method is confirmed to be accurate and effective through comparisons with previous solutions. The results study show that rock mass saturation significantly influences slope stability, with a sharp decline in stability observed at saturation levels below 0.6, and a more gradual stabilization beyond this point. The slope stability factor decreases significantly with the increase of the constraint width of the failure mechanism, indicating the importance of the 3D effect in slope stability analysis. The results provide practical insights for engineering applications.

期刊介绍： Environmental Earth Sciences is an international multidisciplinary journal concerned with all aspects of interaction between humans, natural resources, ecosystems, special climates or unique geographic zones, and the earth: Water and soil contamination caused by waste management and disposal practices Environmental problems associated with transportation by land, air, or water Geological processes that may impact biosystems or humans Man-made or naturally occurring geological or hydrological hazards Environmental problems associated with the recovery of materials from the earth Environmental problems caused by extraction of minerals, coal, and ores, as well as oil and gas, water and alternative energy sources Environmental impacts of exploration and recultivation – Environmental impacts of hazardous materials Management of environmental data and information in data banks and information systems Dissemination of knowledge on techniques, methods, approaches and experiences to improve and remediate the environment In pursuit of these topics, the geoscientific disciplines are invited to contribute their knowledge and experience. Major disciplines include: hydrogeology, hydrochemistry, geochemistry, geophysics, engineering geology, remediation science, natural resources management, environmental climatology and biota, environmental geography, soil science and geomicrobiology.
