Erosion Failure of Slope in a Dump with Ground Fissure under Heavy Rain
نویسندگان
چکیده
The dump, with the compact rock platform and high steep loose slope that is formed during coal mining, most serious area of soil erosion in a surface mine. Ground fissures are typical geological hazard mining areas. However, effect ground on remains unclear. Rainfall experiments were conducted to determine varying characteristics wetting front, runoff sediment production, denudation rate, as well effects these factors platform-slope system dump. could significantly enhance front erosion. Rill was rainfall flushed soil, which eventually developed into gullies. Erosion failure modes systems dump be divided stage, fissure deformation rill collapse-rapid increase stable stage. Runoff power flow shear stress had greater influence indicated energy concentrated important Moreover, shallow mudflow induced by one forms instability; it occurred short time great Soil mainly erosion, resulting from combined hydraulic gravity

Slope Stability Analysis Under Combined Failure Criteria
Strength reduction finite element method (SRFEM) has been widely used to analyze the slope stability. Strength Reduction Factor (SRF) is yielded as the slope Factor Of Safety (FOS) when a running-though shear failure zone comes into being, in which the Plastic Element EQuivalent strain (PEEQ) is employed as the judgment of shear failure initiation in this paper. Moreover, the filed variable is ...
متن کاملTemporal Variation of Interrill Erosion Affected by Slope Gradient in Soils with Different Texture
The process of splash of soil particles by raindrops and their transport by splash or surface shallow flow is considered as interrill erosion, which can reduce soil fertility and cause pollution of surface water. This research was carried out to investigate the temporal variation of interrill erosion in different soils affected by surface slope. For this purpose, laboratory experiments were car...
متن کاملCheck the Soil Yield Stress in Situations with different Slope on a Hill Slope with Pasture Cover with the Occurrence Sulification Erosion
One of the most important types of water erosion, is massive erosion. Soils with fine particles (especially silt particles) have little stability against erosion, because they have more water holding capacity and thus increase the saturation moisture and the likelihood of this type of erosion. So In this study, to investigate the relationship between particle size of silt, with behavior and rhe...
متن کاملStatistical Analysis of Rain Fade Slope
The fade slope is a stochastic parameter and varies with time. The probability distribution of fade slope can depend on attenuation, on the drop size distribution and therefore on the type of rain, and on the wind velocity perpendicular to the path. Furthermore, if several rain cells and/or different kinds of rain may be present, the fade slope is likely to decrease with path length, and theref...
