slope stability is one of the major and determiner parameters in the economy and safety of open pit mines. failure and consequently rupture of the slope caused no compensable economic and humanity losses. so, probability assessment of the further failure for presentation of damages and additional costs is of prime importance. in this research, stability analysis and probability assessment of th...
For the sustainability of lignite and coal mining, engineers need soils' appropriate geotechnical characterisation excavations. This relates to slope stability, overall area sustainable exploitation mining areas during operational post-closure eras. work presents a novel perspective on soil mine Rather than focusing one particular mine, comprehensive provides insights about soils related areas....
The conventional method to evaluate earthquake induced permanent deformations of slopes is the one proposed by Newmark. In this paper, permanent displacement of slopes is studied using a combination of distinct element and finite difference methods and the results of these numerical evaluations are compared with those of the Newmark's approach. Several parameters involved, including peak ground...
Recent research recognized that the slope of 18% can be used to distinguish between ‘gentle slope’ case and ‘steep for detected differences in hydraulic variables (flow depth, velocity, Reynolds number, Froude number) those representatives sediment transport capacity, actual load). In this paper, using previous measurements carried out mobile bed rills flume experiments characterized by steep s...
A new landslide mobility parameter that takes the friction angle into account can shed new light into the dynamics of large Martian landslides. Introduction: Landslide morphologies have been identified on Mars [1-2]. Some similarities between experiments on dry granular spreading and Large Martian Landslides (LML) convey to conlude on dry conditions [3]. However, normalized runout on Mars is tw...
Stability of foundations near slopes is one of the important and complicated problems in geotechnical engineering, which has been investigated by various methods such as limit equilibrium, limit analysis, slip-line, finite element and discrete element. The complexity of this problem is resulted from the combination of two probable failures: foundation failure and overall slope failure. The curr...
Pusa village is located in the karst mountain area of Nayong County, Guizhou Province, China. Laoyingyan rock gently dipping, upper part consists hard formations, and lower made up soft composed 3 coal seams. On August 28, 2017, a massive landslide occurred this area, resulting 82,3000 m3 debris, which resulted significant casualties brought malaise society. In paper, geological conditions long...
Landslide is one of the major natural hazards the world is facing. It happens as a result of both man-made as well as natural factors. It causes severe effects on the environment as well as for the mankind. The main triggering factors of landslide are rainfall/snowfall, tectonic activities and human activities. There are many methods adopted for controlling landslides. The study was carried out...
چکیده به منظور درک بهتری از حرکت صفحات تکتونیکی، می توان از شبیه سازی عددی به عنوان یک ابزار مهم و نیرومند استفاده نمود. لذا بر اساس قوانین فیزیکی و ژئوفیزیکی و در نظر گرفتن نحوه ارتباط و شکل صفحات، می توان رفتارهای آنها را در شرایط متفاوت مدل سازی نمود. نواحی مختلف به دلیل شرایط متفاوت ساختاری، رفتار لرزه ای مشابه ای را نشان نمی دهند. هدف این تحقیق بررسی الگوهای رفتاری مواد با ویژگیها ی مت...
In recent years, autonomous vehicles and advanced driver assistance systems have drawn a great deal of attention from both research industry, because their demonstrated benefit in reducing the rate accidents or, at least, severity. The main flaw this system is related to poor performances adverse environmental conditions, due reduction friction, which mainly state road. paper, new model-based t...
