  • Should Your Sensor Have A Connector Or Pin Terminals?

    When it comes to measuring the activity of your project, it’s nice to have options. High precision sensors can offer plenty of selections from the range of your measurements to the output of your readings, but a sensor is only as good at its connection. Connectors and pin terminals are common and dependable connections that relay your readings from within the sensor to the screen in front ...

  • Waste Rock Back Analysis

    On October 4, 2004, during field measurements collected in trench LFG-008, a crack developed in the middle of the trench. This occurred during the destruction of the Goat Hill North (GHN) rock pile at the Questa site. The crack varied in width up to a maximum of 100 mm and extended in an arc pattern around the pushed out section of the slope. The slope had been pushed in a convex arc out from the ...

  • Why perform 3D slope stability analysis

    Background The benefits associated with performing 3D slope stability analyses were expounded by Dr. Del Fredlund in the 1970s.  Over the years a number of 3D methods of analysis have been researched. These methods have ranged from the method of columns to approaches based on variational calculus, and more recently, the use of dynamic programming. The interest in 3D slope stability analysis ...

  • Random fields in SVSlope and SVFlux

    Geotechnical engineering, as a general practice, has always struggled with quantifying the significant amount of variability that can be present at any given site. There may be variability present in field sampling methods, equipment, lab testing procedures, level of training of field personnel, or many other such factors. One particular problematic aspect of slope stability analysis is the ...

  • Alternate point estimation method

    One of the primary drawbacks to a Monte Carlo analysis is the large number of model runs required in order to determine the relative confidence of each input variable on impacting the factor of safety. The Alternate Point Estimation Method (APEM) allows a dramatic reduction in the number of model runs required to do a statistical analysis. The following table indicates the number of model runs ...

  • 3D Levee intersection analysis

    Levee analysis is becoming an increasingly important topic as the infrastructure ages. Many sections are in need of re-engineering improvements as consideration is given to their replacement. Concepts utilized in their original design are being re-examined. Many of these structures were designed 20 to 50 years ago, and the tools utilized in such analysis have changed significantly. Our ...

  • Balefill Slope Stability Analysis

    The unique ability of SVSlope to search for the most critical slip surface has application in the area of balefill slope stability analysis. In a balefill, the incoming waste stream is compacted into rectangular bales prior to landfilling. Balefills are operated separately from landfills, where the incoming waste is usually condensed in-situ by compactors. The study outlined in this article ...

  • Effect of weathering on the gravitational stability of Questa rock piles

    The Questa Rock Pile Weathering and Stability Project (QRPWASP) is a scientific research project whose purpose was to determine how and to what extent weathering affects the gravitational stability of the Questa mine-rock piles in 100 and 1000 years. The project studied a theoretical composite rock pile taking characteristics from several on site, and was not a site-specific engineering or ...

  • Slope stability analysis of a borax stockpile site

    Stability investigations were conducted for a slope at the back of a borax stockpile site near the Bandirma Harbor in the northwestern Turkey. There was a slope failure at the site causing damage in the concrete sections of the harbour in front. Investigations started with deformation monitoring with an inclinometer. Failure mechanisms were determined with back analysis using method of slices and ...

  • Effect of Rib Spacing on Deformation of Profile-Wall Plastic Pipes Buried in Coarse Granular Backfill

    Several different types of plastic pipe products were instrumented, buried in coarse granular backfill, and subjected to monotonic, distributed load in the field. During each field test, data were recorded from strain gages, linear variable differential transformers, and earth pressure cells by computerized data acquisition units.Review of the deflection data from 14 tests revealed a pattern on ...

  • Drift of Flush-Mounted Pressure Cell Readings

    Readings from earth pressure cells that were flushmounted in an instrumented retaining wall exhibited progressive change with time (drift) after backfill placement. The test procedures and conditions precluded the possibility that temperature effects could account for the drift. A series of experiments showed that the drift was caused by moisture migration from the backfill to the concrete ...
