  • The Basics of Slope Stability Analysis for Geosynthetics

    Slope stability analysis is vital to preventing slope failures in a variety of engineering applications including landfill design, roads, dams and embankments, to name a few. Proper analysis anticipates both natural and manmade slopes and failure of foundations and retaining walls. This blog covers the necessity of slope stability analysis, how to conduct the analysis and the role of ...

  • Using Geosynthetics in Slope Stability

    The majority of slope failures within the geosynthetics industry can often be avoided with proper engineering and material selection. However, the factors that affect slope stability can be difficult to discern and measure. Soil thickness, seepage forces, seismic forces, gas uplift, geomembrane texturing, engineering and provision of reinforcing elements are only a few of the factors affecting ...

  • 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 ...

  • Erosion control and slope stability project case study

    The steep un-vegetated slope at this lakeshore residence was eroding into the lake with every rain event. Record high lake levels combined with wave action eroded the base of the hillside causing severe hillside instability. During heavy rainfall events more and more of the hillside slipped into the stairwell and lake. The residence owner was concerned with preserving the slope, overlook ...

  • Stream restoration and slope stabilization project case study

    ‘Gerber Legendary Blades’, a division of Fiskars, is a manufacturer of jack-knives for outdoors enthusiasts. The Gerber corporate headquarters was built in the late 1970’s near Portland, Oregon. The parking lot was built an adequate distance from the stream running through the property, and paved with asphalt. In the late 90’s, continued development of impervious surfaces ...

  • 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 ...

  • Geodrilling: Maintenance of active slope stability installations

    Landslide activity and slope failure on parts of the Isle of Wight have been an ongoing problem for hundreds of years and a significant landslide during the particularly bad winter of 1994-5 seriously affected an area up to 400 metres inland from the coast. Instability in the Castlehaven area had to be addressed to reduce the risk to public safety, property and the local infrastructure. The Isle ...

  • 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 ...

  • Laboratory Testing Apparatus for Slopes Stabilized by Anchored Geosynthetics

    A laboratory testing apparatus is described for examining slopes subjected to seepage and stabilized by anchored geosynthetics (AGS). The AGS technique can increase the stability of cohesionless slopes such as coastal dunes against surficial erosion and shallow mass failure caused by wave action and seepage forces. In the AGS, a geosynthetic fabric is placed on the face of the slope and tensioned ...

  • Purpose-Driven Public Sector Reform: The Need for Within-Government Capacity Build for the Management of Slope Stability in Communities in the Caribbean

    Abstract This article stresses the importance of within-government capacity build as the optimal approach to minimizing landslide risk to the most vulnerable communities in the developing world. Landslide risk is an integrated issue that demands strong managerial leadership and multidisciplinary inclusion to develop structures that deliver sustainable improvements in the reduction of risk. The ...


  • Ohio slope erosion, Cleveland, Ohio

    Every day, over 100,000 vehicles drive on I-480, a six lane Interstate highway around Cleveland, Ohio. To improve the appearance and correct some heavily eroded areas, the Ohio Department of Transportation decided to landscape 3.5 miles (5.6 km) of both cut and fill slopes on the north side of I-480. Their plans called for regrading, draining, and planting trees, shrubs and various plants. ...

  • Virginia dOT slope protection, Collinsville, Virginia

    Prior to 1988, the sandy clay embankments along Route 220 near Collinsville, Virginia were subject to severe erosion and loss of vegetative cover, particularly after heavy rainfalls. The problems were most severe on embankments with steep slopes. These problems persisted despite numerous attempts to stabilize the soil and control surface erosion. In April of 1988, the Virginia Department of ...

  • Slope failures in municipal solid waste dumps and landfills: a review

    Between 1977 and 2005 six large-scale failures of municipal solid waste dumps and landfills have been recorded in the technical literature. The volumes of waste mobilized in the failures varied from 10—12 000 m3 in a failure that killed nearly 300 people to 1.5 million m3 in a failure that caused no deaths or injuries. Of the six failures, four occurred in dumps that, as far as is known, had not ...

  • Geotex® 4x4 used in Missouri slope failure repair project case study

    In 1993, flooding in an adjacent stream caused a slope failure along a 300 foot section of Old Highway 100 in Franklin County, Missouri. Many attempts were made over the years to stabilize the slope and roadway, and none were successful. Flooding caused the slope that supported the highway to give way and become hazardous. A porous concrete slope protection facing was used to cover approximately ...

  • Gaviota pass steep slope, Santa Barbara County, California

    Faced with repair of a severely eroded steep section of pipeline right-of-way on the California coast, engineers determined that GEOWEB Cellular Confinement System was the only system capable of providing a cost-effective and appropriate solution. With a total slope length of 500 feet, a severe pitch of 1:1 and bare rock slope faces, four inch deep GEOWEB was installed in order to “perch” soils ...
