Dynamic Responses of Weathered Rock Slopes Under Harmonic …
2023年3月3日 · Here, the dynamic response and failure mode of a weathered rock slope under the action of harmonic waves with different peak accelerations was studied using the shaking table test. Three quantitative indexes of slope damage were then proposed.
Influence of surface wave impedance ratios on the dynamic …
2024年4月1日 · Weathered slopes are often severely damaged during earthquakes, posing challenges to the study of their dynamic response and damage characteristics. In this study, we conducted physical modelling tests using the wave impedance ratio to investigate the influence of weathering layers on slope dynamics through shaking table tests.
Uncoupled analysis of stabilizing piles in weathered slopes
2003年12月1日 · To examine the most effective means of using piles for stabilizing slopes, a series of numerical analyses on stabilizing piles were performed based on the major influencing parameters such as the spacing between piles, cap rigidity, the relative position of the pile row on the slope, and profiles of lateral soil movements.
Stability Analysis of Strongly Weathered Muddy Slate Slopes
2023年10月11日 · Drawing from shear strength parameters and the water immersion softening observed in laboratory and in-site tests, we formulated a numerical slope model that considers layered structures and water immersion conditions to evaluate slope stability.
In this paper the authors describe some of the processes that should be considered when attempting to establish the strength and failure envelopes input into slope designs for open pits in weak rocks. ‘Guidelines for Open Pit Slope Design’ was produced in …

2024年1月24日 · Rock slope failure along road cuts in weathered elevated terrains is a frequent geotechnical issue. The slope stability probability classification (SSPC) system is commonly employed as a reliable, systematic, quick, and probabilistic approach to …
Slope stability analysis under heavy rainfall considering the ...
2024年12月12日 · The findings indicate that the Weibull distribution is a convenient and relatively precise method for characterizing the heterogeneity of weathered layers in slopes. Consequently, selecting an appropriate heterogeneity index m is crucial for accurately assessing slope stability. This study also concludes that the dissipation of matric suction ...
Model Test Study on Response of Weathered Rock Slope to …
Weathered rock (especially granite) slopes are prone to failure under the action of rainfall, making it necessary to study the response of weathered rock slope to rainfall infiltration for landslide prevention. In this study, a series of model tests of weathered rock slope under different conditions were conducted.

2010年7月22日 · Shallow soil slips evolving to rapid and catastrophic debris flows are probably the most common type in steep residual soil slopes, whereas thicker failures, also including deep-seated complex...
Impact of weathering on slope stability in soft rock mass
2014年6月1日 · The problem of stability over time should be considered for slopes excavated in soft rocks, in case they are not protected against weathering processes. In addition to disintegration of material on slope surface, the weathering also results in shear strength reduction in the interior of the slope.
