  • Geotechnical Properties of Municipal Solid Waste

    A geotechnical testing program was conducted to evaluate the engineering properties of aged solid waste samples retrieved from a landfill that began accepting waste as early as 1940. The conducted tests included water content, specific gravity, Atterberg limits, grain-size distribution, compaction, permeability, consolidation, triaxial, and direct shear. Maximum dry unit weight achieved using the ...

  • Testing of Geotechnical Fabric for Use as Reinforcement

    Twenty-seven commercially available petrochemical-based geotechnical fabrics, both woven and nonwoven, and one fiberglass fabric were evaluated for suitability as reinforcement in an embankment test section to be constructed on soft foundation at Pinto Pass in Mobile Harbor, Ala. by the U.S. Army Corps of Engineers Mobile District. All fabrics were subjected to initial testing in uniaxial tension ...

  • Evaluation of Shear Strength in Cohesive Soils with Special Reference to Swedish Practice and Experience

    The paper describes how the Swedish Geotechnical Institute (SGI) currently proceeds in the evaluation of shear strength in cohesive soils. Information is given on how different test results and empirical experience can be weighted and combined to give the best possible estimation of the shear strength properties in cohesive soils. The procedure described has evolved during the continuing work at ...

  • Assessment of geo-hazard potential and site investigations using Resistivity Imaging

    The use of geophysical methods for evaluating subsurface contamination of sites is becoming increasingly popular all over the world. The paper presents the assessment of geo-hazard potential of a site in the City of Duncanville, Texas using Resistivity Imaging (RI). Resistivity Imaging was being used to identify areas of environmental concern and to develop a detailed image of subsurface ...

  • A New Approach to Measuring Dilatancy in Saturated Sands

    The determination of in situ properties of sand has proven to be a difficult objective, especially when it includes assessing volume change characteristics like dilatancy. Difficulty in obtaining representative undisturbed specimens as well as problems with extrapolating laboratory test results to the field has caused many to place increased reliance on in situ testing. One such test that is ...

  • Decontamination of soil contaminated with petroleum grease

    Contamination modifies the engineering properties of soil, thereby restricting its further use either as a construction material or as a supporting medium. Due to the scarcity of land, it becomes imperative to reuse the land for infrastructure developmental activities. Out of numerous soil contaminants, automobile grease is one of the most prominent. Considering the cumulative impact of ...

  • Uniformity Tests in Calibration Chamber Samples by the Thermal Probe Method

    The calibration of geotechnical instruments for in-situ tests, performed on sand samples reconstituted in huge calibration chambers (CC), requires the reproduction of large specimens at given relative densities with good repeatability and satisfactory homogeneity. A test method has been developed with the purpose of evaluating the relative density, DR, in different locations of the CC samples ...

  • 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 ...

  • Lessons Learned from Large Diameter Sanitary Sewer Pipe Bursting Project: Conversion of Abandoned Gravity Sewer Main Into Upsized Sanitary Force Main South San Francisco, CA

    ABSTRACTAs an increasing number of large diameter pipe bursting jobs are attempted, more is being learned about the capabilities and potential of pneumatic pipe bursting. The large diameter pipe bursting project in South San Francisco is one of the most challenging and innovative bursting projects ever attempted in North America. It is being heralded as a landmark pipe bursting job. ...

  • Water and wastewater projects in Jordan

    About 70% of Jordan has an annual rainfall of less then 100 mm. The population and water demand have increased during the last years and the groundwater resources are in danger of drying out. As the population continuous to grow it is necessary to find new resources to meet future demands of water for municipal, industrial and irrigation purposes. The two projects, As-Samra and Disi, aims to ...

  • Varian Semiconductor Equipment Assoc. Inc. – Gloucester, MA - Case Study

    Producing the heavy equipment that makes semiconductors and other chips demands a tremendous amount of electricity, so this publicly-traded company sought ways to cut massive utility bills and pursue renewable power sources. Varian Semiconductor Equipment, a division of Applied Materials Inc., is located in an industrial park in Gloucester, MA. The Cape Ann hilltop location offered prospects for ...

  • Staying Safe with Environmental Monitoring

    Geotechnical Instrumentation involves administering the earth and environment and it is hence that designers have made different frameworks to make the occupation simpler. These frameworks grab thousands upon much information that it orders and illuminates so they can concoct evidence. The places where it is necessary are the pollution chance appraisal, trends in time and space; anticipatory ...

  • Donzi landfill expansion using stratagrid case study

    Background The Donzi Lane Landfill in Atlanta, GA had been in use since the 1970's for construction and demolition waste disposal. The site was nearing its capacity and additional landfill space was urgently needed due to the accelerating population growth and waste stream generated by development. Due to the high cost and long lead times for designing, permitting and constructing new ...

  • Notus Clean Energy LLC – Cape Cod, MA - Case Study

    The owners of a Falmouth, MA industrial park parcel saw the potential in 2004 for a utility-scale wind turbine sited in a large, well-elevated location. A large turbine could supply electricity for the complex and create surplus power that could be delivered back to a regional utility. Despite receiving more than 100 letters of support from residents and businesses, the proposal required five ...

  • 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 ...
