The aim of this study is to investigate the influence anisotropic variability in soil on failure mechanism and ultimate bearing capacity foundations that are placed near slopes. A random adaptive finite-element limit analysis (RAFELA) with field modeling Monte Carlo simulation technique combined. stochastic for various undrained shear strengths, slope angles, normalized heights, distances from crest, horizontal vertical correlation analyzed. quantitative identification characterization...
The bearing capacity of shallow foundations may decrease when located near slopes, particularly under seismic conditions. However, there is limited work that isolates the destabilising influences seismicity and finite slope geometry on ultimate in terms conventional factors. Herein, analytical solutions based upper-bound kinematic limit analysis are used to isolate both mechanism failure factors (N c , N γ q ) for slopes subject action without using principles superposition. show good...
This paper focuses on the bearing capacity of vertically loaded rigid footings adjacent to slopes with spatially random soil by performing adaptive finite-element limit analysis. The solution is illustrated quantitatively assessing effect influential factors, taking into account spatial variability, properties, and geometric parameters ultimate failure mechanism. variability slip surface, which has several mechanisms, investigated for various normalized slope heights, footing distances,...
For conventional assessment of the bearing capacity shallow foundations on level ground, dimensionless factors are used to establish contribution footing size, embedment, and soil shear strength. This study presents derivation an analytical approach toward evaluating influenced by presence a slope. The results presented as (Ncs, Nγs, Nqs) enabling consideration cohesion, weight, embedment in calculation near slopes. nature work provides insight into influence critical...
Although mechanically stabilized earth (MSE) walls typically require a reinforcement length-to-wall-height ratio of 0.7, the use short may be inevitable in certain situations, such as building MSE mountainous areas, widening existing highways, or restoring eroded roadways. Intuitively, connecting rear end shored (SMSE) to stable face behind can compensate for insufficient anchorage length. However, effectiveness this approach remains debatable literature. This study aims provide more...
Slopes forming convex corners are often constructed in practice. Observed failures of such possess three-dimensional (3D) characteristics. Hence, assessing corner stability requires 3D analysis. This study used a variationally derived mechanism to analyze the turning corners. Results analysis presented convenient form charts considering effects pore-water pressure and seismicity. These allow for quick assessment factor safety. Stability increases as its angle decreases. When subjected...
