Research ArticleOpen accessIn the keywordsStability Analysis of Southern Slope of Chenmenshan Open Pit Copper MineMohammed Mnzool, Ling Wan, Zuoan WeiChengmenshan Copper SulphurMine, one of the of the large-scale open pit mine in China, the engineering geology and hydrogeology in the Southern slope of the mine is very complicated and the contact plane between two kinds of sandstone’s form soft-weak layer. Field investigations and reports by operators demonstrated that some instability problems might occur in the southern slope which is … …Current Research in Geoscience, Vol. 3, Issue 1 · 4 Sep 2013 · 6,970 accessesView PDFCite
Research ArticleOpen accessIn the keywordsKey Factors in the Face Stability Analysis of Shallow TunnelsDaniel Dias, Pierpaolo OresteStability of the excavation face in shallow tunnels and in poor ground is at present a relevant problem in tunnelling. A new calculation procedure is illustrated in this study for the analysis of the effect on the face stability in shallow tunnels of the following key factors: pre-support structures, presence of groundwater, free length of the tunnel (length of the … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 7,017 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstablishment of Readily Mathematical Formulation for the Evaluation of Slope Stability in Earth-Fill DamsSalah Saleh, Majda Ibobakr Almhdi AmerThe assessment of slope stability has been considered to be one of the most common issues to deal with by geotechnical engineers. This is due to the amount of destruction that can be brought up by the slope failure of soil masses to roads, railways, and earth dams, for example. Therefore, the stability of soil mass slopes must be carefully … …Journal of Mathematics and Statistics, Vol. 19, Issue 1 · 13 Nov 2023 · 5,181 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Mercury and Manganese by Using New Reagent Azo after Cloud Point Extraction for Some Environmental Sample in IraqSaadiyah Ahmed DhahirA new reagent of Azo was papered for determination of Hg+2 and Mn+2 by Cloud Point Extraction (CPE) method. Procedure which was developed for the separation and preconcentration and the procedure are simple, cheap, fast and environmental safety. The parameters affecting could point extraction, such as concentrations of reagent, volume of triton X-100, pH, equilibrium of temperature and time-consuming were … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 19 Nov 2015 · 6,971 accessesView PDFCite
Research ArticleOpen accessIn the abstractRiver Embankment and Bank Failure: A Study on Geotechnical Characteristics and Stability AnalysisMd. Bellal Hossain, Toshinori Sakai, Md. Zakaria HossainProblem statement: Embankment failure and riverbank erosion are common problem in Bangladesh. Almost every year earthen embankments and riverbanks are facing problems like erosion, breaching or retirements. Among many reasons the major causes are considered due to the use of geotechnically unstable materials, improper method of construction, seepage and sliding. In this study the problem is considered geotechnical point of … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 11,002 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarthquake Resistant Design of Reinforced Soil Structures Using Pseudo Static MethodB. Munwar Basha, G.L. Sivakumar BabuProblem statement: This study presented a method to evaluate the internal stability of reinforced soil structures against tension and pullout modes of failure using pseudo-static method for earthquake conditions. Approach: Using limit equilibrium method and assuming the failure surface to be logarithmic spiral, analysis was conducted to maintain internal stability against both tensile and pullout failure of the reinforcements. For … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 7,572 accessesView PDFCite
Research ArticleOpen accessIn the abstractStability Analysis and Stability Chart for Unsaturated Residual Soil SlopeBujang B.K. Huat, Faisal Hj. Ali, R. S.K. RajooIn tropical residual soils most hill slope failures are caused by rainfall. It is therefore important to consider dynamic hydrological conditions when attempting to analyze the stability of residual soil slopes. This paper describes a coupled hydrology/stability model that has been developed to overcome the limitations of the standard method of analysis used to investigate stability of tropical soil slopes. … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 7,325 accessesView PDFCite
