  • Modeling Pinch-Outs and Steep Topography in RockWorks - Case Study

    Summary Areas with complex stratigraphy (i.e. pinch-outs, folding, faults, etc) are not easily modeled in the borehole manager. One will often have to take the grids originally created with the borehole manager and manipulate them in the Utilities or in other programs. There are several tools available is the Utilities for manipulating your grids. Once you have edited your grids, you can ...

  • 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 ...

  • Model Size Effects in Centrifuge Models of Granular Slope Instability

    Two assumptions behind geotechnical laboratory testing are: first, that soil with grains small enough to behave as a continuum in a full-scale field situation will also behave as a continuum in a small laboratory test; and, second, that side boundary effects in a laboratory test are either negligible or, if not negligible, do not dominate behavior but are quantifiable so that a correction can be ...

  • Measurement of In Situ Density of Sand in a Chamber by Using a Thermal Conductivity Penetrometer

    Reliable in situ testing during soil exploration is of great help to geotechnical engineers in design considerations. This paper describes the theory and the laboratory test results for determination of the density of a sand with a quasi-static penetrometer by measuring its thermal conductivity. Effects of disturbance caused by the penetrometer have been studied. It is shown that it is possible ...

  • 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 ...

  • Determination of Swell Potential of Al-Qatif Clay

    Knowledge of the swell potential of expansive soil at the outset of an investigation can be helpful in avoiding possible damage to the structure. A review is presented of several methods that have been proposed to identify swell potential and test techniques, which are used to quantify the amount of swell. A site investigation was conducted to obtain hand-carved block specimens from a fresh ...
