Determining Important Grade of Environmental Risk Factors at Slopes

Abstract— Both, natural and man-made slopes formed for various purposes may cause numerous permanent problems in engineering applications. Therefore, it is important to know composition and mechanical behavior of soil environment leading to geotechnical problems on slope surfaces. The risk analyzes of natural and artificial slopes, realized detailed, can lead to reliable results. Based on those results, it is possible to produce optimal technical solutions with respect to an acceptable risk level. The researches on these subjects give new opportunities to improve the existing knowledge by reviewing them. The main aim of this study is objectively to evaluate the parameters caused slope stability problems. In this regard, the parameters of slope angle, internal friction angle and cohesion of soil, and groundwater level, which are main risk factors for a slope, and should contribute to raise awareness about this issue, were investigated.
