WebApr 13, 2024 · The quantitative evaluation of slope stability under rainfall action is usually carried out in two steps. First, a suitable rainfall infiltration model is selected to determine the seepage field. Then, the stability analysis method is used to calculate the SF. It is also the main concern of stability evaluation of landslide caused by rainfall. WebFor infinite slopes that have seepage at the slope face, the factor of safety for slope stability is determined as follows: (7-2) where, γ. b = the buoyant unit weight of the soil γ. s = the saturated unit weight of the soil Tan Tan FS Tan Tan FS b Slope Stability Analysis …
WebJul 21, 2024 · GEO-SLOPE , PLAXIS , and Soil Vision , which are based on FEM programs, are widely used [18,19,20,21] for simulating the seepage problem and slope stability. Where a major part of the slip surface is below the groundwater table, the shear strength contribution from negative pore-water pressures above the groundwater table is often ignored by ... WebApr 15, 2024 · Suffusion is a typical kind of internal erosion that changes the permeability property of soil without destroying its structure. A horizontal laboratory test was conducted to analyze the permeability property variation in sandy soil caused by suffusion, and the content of fine sand (R f) varied from 5 to 25%.Water-level along the seepage path is …
Webthe soils may also be required. Although these methods define movements and stresses through-out the slope, they do not provide a direct measure of stability, such as the factor of safety calculated by limit equilibrium analyses. The focus in this chapter is on soil slopes and mechanisms involving shear failure within the soil mass.
WebJan 13, 2024 · Many studies analyze the influence of rainfall on slope stability, and two main methods are utilized: (1) field investigations and monitoring data analysis through model tests [ 20 – 23] and (2) numerical simulations, such as the finite element method and finite difference method [ 24 – 28 ].
