Methods and applications of ERS SAR interferometry for monitoring mass movements on mountain slopes and surface deformation in volcanic areas have been investigated in order to explore the operational potential of interferometry for the assessment of natural hazards. A statistical analysis was carried out in a region of the Eastern Alps to study the potential of SAR for monitoring slope motion ...

The objective of this paper is to present a new rock mass classification system which can be appropriate for rock slope stability assessment. In this paper an evaluation model based on combining the Analytic Hierarchy Process (AHP) and the Fuzzy Delphi method (FDM)was presented for assessing slope rockmass quality estimates. This research treats the slope rockmass classification as a group deci...

How to quantitatively characterise the impact of underground coal mining on stability and slippage loess slopes is a key problem in evaluation damage under slopes, but it more difficult study this particular mechanical properties topographical features slopes. In order clarify seam slope, theoretical analysis, numerical simulation physical similarity experiments are used address based theory sl...

We study internal wave generation in a laboratory model of oscillating tidal flow on a continental margin. Waves are found to be generated only in a near-critical region where the slope of the bottom topography matches that of internal waves. Fluid motion with a velocity an order of magnitude larger than that of the forcing occurs within a thin boundary layer above the bottom surface. The reson...

A sandpile with two stable and two unstable ranges of slopes is presented as a minimal model for the study of H-mode pedestal formation and dynamics. Pedestals are observed to form and expand inward with increasing deposition. Transport bifurcation is not critical to pedestal formation, though the pedestal structure obtained with a second, hard stability boundary is qualitatively different from...

The primary aim of every twenty-first century mining operation is to extract as much ore possible in a safe and economical manner. Failure mine excavation occurs when the shear stress acting on rock greater than strength mass. stability slopes open-pit quarry operations extremely important from both economic safety points view because unstable can result loss human life damage properties. This ...

Understanding the failure mechanism and modes of multiface slopes in Wenchuan earthquake can provide a scientific guideline for slope seismic design. In this paper, two-dimensional particle flow code (PFC2D) shaking table tests are used to study slopes. The results show that with different moisture content under loads. 5%, 8%, 12% shattering-shallow slip, tension-shear shattering-collapse respe...

Undrained instability is a failure mode that has been observed in many sandy slopes. However, the highly anisotropic stress states caused by geometry of slope have not duly considered from experimental point view. This article studies influence initial anisotropy laboratory samples on static undrained Colombian reference sand. Forty-five consolidated triaxial tests were performed, prescribing c...
