Ridge slopes often occur in highway or railway engineering. The initial stress distribution of a ridge slope is important for the original and an excavation slope. In this paper, wire-frame model was established. Numerical simulations on 3D stability analysis were performed using strength reduction method based unified theory. influences ridgeline dip angle α, flank β, height H deformation fail...

Quasi-steady gravity currents propagating first on a horizontal and then up sloping boundary are investigated by means of theoretical analysis laboratory experiments. The bottom slope ranged from 0.18 to 1 full- partial-depth configurations were considered. developed model, using the depth averaged momentum equation, provides new physical insight into importance different forces that act curren...

Through a sample survey of the research area Yunnan Agricultural University (YAU) Research Base in Malong Jiuxian County, we summarized types herbaceous vegetation communities terraces ecological isolation zone area, analyzed species’ importance value, Patrick index, Simpson Shannon-wiener and Pielou then explored different patterns (annual two-years artificial sowing natural secondary communit...

A unique description for highly nonlinear potential water waves is suggested, where weak three-dimensional effects are included as small corrections to exact two-dimensional equations written in conformal variables. Contrary to the traditional approach, a small parameter in this theory is not a surface slope, but it is the ratio of a typical wavelength to a large transversal scale along the sec...

In this paper we construct a numerical solver for the Saint Venant equations. Special attention is given to the balancing of the source terms, including the bottom slope and variable crosssectional profiles. Therefore a special discretization of the pressure law is used, in order to transfer analytical properties to the numerical method. Based on this approximation a wellbalanced solver is deve...

Abstract Intruding slope water is a major source of nutrients to sustain the high biological productivity in Gulf Maine (GoM). Slope intrusion into GoM affected by Stream warm-core rings (WCRs) impinging onto nearby shelf edge. This study combines long-term mooring measurements, satellite remote sensing data, an idealized numerical ocean model, and linear coastal-trapped wave (CTW) model examin...

The microtopographic changes induced by coal mining subsidence caused a series of environmental problems such as soil erosion, and vegetation degradation in the area. However, corresponding influence on surface characteristic different parts slope was completely different. To understand mines their future ecological restoration, it crucial to investigate origin. relationship between microbial c...

Two dimensional slope profile morphometric investigation in a part of the land failure prone Garhwal region of the Lesser Himalaya, Tehri district, U. P., India, indicates that the landslip morphology is closely related to the dominant movement processes active in this terrain. Technique developed for the morphometric analysis of landslips involves the use of five morphometric indices. Each ind...

The weak interlayer in the slope meets with water threatening overall stability of slope. Sequestration location layer has an impact on Based this, taking south-side Fushun West Open-Pit Mine as background, limit equilibrium method was used to study influence different depths and dip angles interlayers factor-of-safety sliding mode After analyzing effect, a bottom friction experiment conducted ...

Slope stability analysis is one of the most important tools to determine both natural as well man-made slopes. The main objective this study compare safety factor Jure landslide before and after an earthquake occurrence using Geostudio QUAKE/W module. Three different positions water table (top, middle bottom debris) were considered for study. factors deterministic probabilistic case are determi...
