In this study, a low-cost, rapid and qualitative evaluation procedure is presented using dynamic pattern recognition analysis to assess liquefaction potential which is useful in the planning, zoning, general hazard assessment, and delineation of areas, Dynamic pattern recognition using neural networks is generally considered to be an effective tool for assessing of hazard potential on the b...

Earthquake-induced soil liquefaction can cause settlement around piles, resulting in drag load and pile after shaking stops. Estimating the axial distribution is important for designing evaluating performance of axially loaded piles liquefiable soils. Commonly used neutral plane solution methods model layer as an equivalent consolidating clay without considering sequencing pattern excess pore p...

Soil liquefaction has been extensively investigated over the years with the aim to understand its fundamental mechanism and successfully remediate it. Despite the multi-directional nature of earthquakes, the vertical seismic component is largely neglected, as it is traditionally considered to be of much lower amplitude than the components in the horizontal plane. The 2010-2011 Canterbury earthq...

Pulverized Wyoming subbituminous coal was beneficiated by low-pH oil agglomerationat CONSOL to prepare the coal for direct liquefaction. Conventional cleaning is not veryeffective in cleaning this coal; for example, conventional oil agglomeration only givesabout 20% ash rejection. To improve ash rejection, the coal-water slurry was acidifiedto a pH of about 0.5. Oil agglomeratio...

INTRODUCTION Environmental impacts from large-scale commercialization of coal liquefaction are important to government, industry, the public, and a variety of interest groups. This report reviews environmental issues associated with coal liquefaction processes by addressing the following topics: ● A comparison of the environmental differences among technologies; “ A comparison of the impacts am...
