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 ...

We study the exponential stability in H 2 norm of nonlinear Saint-Venant (or shallow water) equations with arbitrary friction and slope using a single proportional-integral (PI) control at one end channel. Using good but simple Lyapunov function we find explicit condition on gain PI to ensure any steady-states. This is independent slope, coefficient, length river, inflow disturbance and, more s...

Abstract In current research, a novel geometrical technique is introduced to estimate the length ( L ) of sliding arc by considering slip surface entry point distance d e ). Morgenstern-Price limiting equilibrium and strength reduction methods are selected within framework SLOPE/W FLAC 3D softwares respectively, study mechanism stability-effecting factor for loose rock slope comprise two differ...

Chemical force microscopy (CFM) was used to probe interactions between ionizable and neutral functional groups in aqueous solutions. Force microscope probe tips and sample substrates have been covalently modified with self-assembled monolayers (SAMs) terminating in distinct functional groups. SAMs were prepared by treating Au-coated or uncoated tips and substrates with functionalized thiols or ...

– We study the direct enstrophy cascade in a two-dimensional flow generated in an electromagnetically driven thin layer of fluid. Due to the presence of bottom friction, the energy spectrum deviates from the classical Kraichnan prediction k. We find that the correction to the spectral slope depends on the thickness on the layer, in agreement with a theoretical prediction based on the analogy wi...

stability of foundations near slopes is one of the important and complicated problems in geotechnical engineering, which has been investigated by various methods such as limit equilibrium, limit analysis, slip-line, finite element and discrete element. the complexity of this problem is resulted from the combination of two probable failures: foundation failure and overall slope failure. the curr...

The shear strength parameters of soil such as cohesion (C) and angle of internal friction (φ )govern the bearing capacity of shallow or deep foundations, the stability of the hill slopes as well as slopes of dams and embankments, design of retaining structures etc. in most of the civil engineering practices. In this study, artificial neural network (ANN) with the feed-forward back-propagation a...

flood flow importance enforces we to simulate its components exactly. in this study, saint-venant equations in conservative form are usedto simulate one-dimensional rapidly varied flow in the river. upstream methods of godunov family in finite volume frame work are used to numerical solution. according to flow conditions in the river, the equations used are included in the source term of the be...

Calculation of lateral earth pressure on retaining walls is one of the main issues in geotechnics. The upper and lower bound theorems of plasticity are used to analyze the stability of geotechnical structures include bearing capacity of foundations, lateral earth pressure on retaining walls and factor of safety of slopes. In this paper formulation of finite element limit analysis is introduced ...

Heavy rainfall can lead to shallow slips in slopes that are initially in a state of partial water saturation. Multiphysics numerical modelling approaches taking into account the involved physical key processes in variably saturated soils during rainfall events could help in understanding the main slip mechanisms. The concerned processes are related to water flow through the solid matrix, soil w...
