the design of appropriate, cost-effective remedial measures requires a clear understanding of the processes that are causing the landslide. this understanding require a detailed site investigation, a reconnaissance of the landslide as soon as possible after it's occurrence can allow important observations of the processes involved. a key step in analyses of soil slope stability is measurin...

the effect of acetate ion introduced to aqueous solutions was investigated for the extraction/separation of ni and co from a dilute sulfate media. the separation of co and ni was improved by introducing acetate to aqueous media. by the use of the slope analysis method,the stoichiometric coefficient of the extractant was found to be 4 for cobalt and 3.5 or 4 for nickel depending on the acetate c...

Abstract In the paper numerical modelling of ensuring slope stability and their analysing with using different methods are presented. We have designed cutting walls earth nails anchors securing for ensuring. The calculate mechanism failure process reinforced slopes were studied stability. nailing significantly increased level Spencer method. Increasing nail or length improved slopes. exhibited ...

This paper addresses the analysis of slope-parametric hybrid automata: nding conditions on the slopes of the automaton variables, for some safety property to be veriied. The problem is shown decidable in some practical situations (e.g. nding the running speeds of tasks in a real time application, for all tasks to respect their deadlines). The resolution technique generalizes polyhedral-based sy...

A practical procedure is described for implementing Spencer’s method of slices with varying side force inclination. The search for the noncircular critical slip surface is accomplished using spreadsheet-automated constrained optimization. The deterministic formulation is then extended probabilistically to compute the Hasofer-Lind reliability index via constrained optimization of the dispersion ...
