The spatial variability of snow stability presents a challenge to avalanche workers and scientists attempting to assess avalanche danger. Recent research has demonstrated, and attempted to explain, snowpack and snow stability variations over individual slopes. However, these studies have provided single snapshots of an exceedingly dynamic system instead of investigating stability variations ove...
in the past, rock slope stability analysis were performed either graphically or using a hand-held calculator, but nowadays there are variety of slope stability analysis which can be used according to the field condition and potential failure mode. in 2-d analysis, effect of convex and concave walls are neglected, however concave slopes are believed to be more stable than straight walls due to t...
rock slope stability depends very much on the strength features of the rock and the geometrical and strength characteristics of the discontinuities (e.g., roughness, wall strength and persistence). since a rock mass is not a continuum, its behavior is dominated by such discontinuities as faults, joints and bedding planes. also, rock slope instability is a major hazard for human activities and o...
در این تحقیق سعی شده است که رفتار شیبهای خاکی ساخته شده در دستگاه میزلرزه دستی با زوایای مختلف، تحت اثر بارهای دینامیکی مختلف اعمال شده بررسی و نتایج آن استخراج گردد تا با بررسی نتایج گرفته شده از مدل سازی شیب، بتوان درک مناسبی از رفتار شیب خاکی در حالت دینامیکی بدست آورد. همچنین مدلهای ساخته شده در آزمایشگاه توسط نرم افزار عددی مناسب، مدل گشته و سپس نتایج بدست آمده از مدلسازی عددی با نتایج آزم...
Quadrupedal robots working outdoors are very slow robots prone to tumble down in the presence of perturbations. This paper presents a novel gaitadaptation method that enables walking-machine gaits to autonomously adapt to environmental perturbations, including the slope of the terrain, by finding the gait parameters that maximize robot’s dynamic stability. Experiments with the SILO4 quadruped r...
by Craig Abram Jordan, M.S. Washington State University Chair: Balasingam Muhunthan Landslides constitute a major geological hazard in the world due to their high financial cost and their nondiscriminatory nature. The Olympic Region of Washington State has many potential triggers of landslides, but prolonged periods of high rainfall is the most commonly attributed trigger of landslides. The cur...
Slope stability analysis is a geotechnical engineering problem characterized by many sources ofuncertainty. In slope stability computations, some of these sources are encountered, such as geologicaldetails missed in the exploration program, estimation of soil properties that are difficult to quantifyand many other relevant factors. Therefore, accurate reproduction of the spatial variability in ...
slope instability due to landslides is particularly common in iran. it is possible to fight against these hazards thanks to the roots of trees, which provide an important contribu-tion towards the stability of hillslopes. however, our knowledge of the effectiveness of roots for slope stability needs improvement. therefore this study was carried out on the effect of tree roots on slope stability...
