Available in PDF, EPUB and Kindle. Book excerpt: Internal instability occurs when the filtrate under the influence of strong seepage forces accompanies the finer fraction from broadly graded granular soils and induces marked changes in its original particle distributions. The changes in particle size distribution may occasionally render the granular filters ineffective in retaining the protected base soils. A prior assessment of internal instability potential is emphasized through some of the well-accepted constriction and particle size-based criteria. The former criteria are too computationally complex to apply in practice, while the latter require only the particle distribution of a soil and are thus preferred by the practitioners for prompt assessments of internal stability. In this study, gradient-controlled hydraulic tests conducted over a range of variably compacted soils were used to analyze some of the existing criteria, which showed partial success in assessing the current test specimens. Further analysis facilitated a useful revision of a well-accepted criterion, which could then reliably interpret the current test results with enhanced accuracy. Additional experimental data from 15 published filtration studies could further validate the current revision, which incorporates both the particle size distribution and relative density of soils, thus making it more appealing for practitioners. Furthermore, a couple of real-life design examples presented to demonstrate the advantages and implications of the current proposition for practical purposes.

Available in PDF, EPUB and Kindle. Book excerpt: Internal erosion and piping in embankments and their foundations is the main cause of failures and accidents to embankment dams. For new dams, the potential for internal erosion and piping can be controlled by good design and construction of the core of the dam and provision of filters to intercept seepage through the embankment and the foundations

Available in PDF, EPUB and Kindle. Book excerpt: Present Corps of Engineer (CE) filter criterion (EM 1110-2-1901, Appendix D) dates from the early 1950's, and some uncertainty exists as to the applicability and adequacy of this criterion under various conditions. Laboratory filter tests were conducted on uniform and poorly-graded cohesionless base materials protected by various filters, and internal stability tests were conducted on various graded filter materials. Based upon the limited tests conducted, the following changes to CE filter criterion are proposed. For a uniform (poorly-graded cohesionless base material, the second stability ratio should not be used, and there is no need for requiring parallelism of filter and base gradations should be retained. For a poorly-graded cohesionless base material, the second stability ratio should not be used, but the requirement for parallelism of filter and base, gradations should be retained. Poorly-graded gravelly sand and sandy gravel are internally unstable and should not be used as filters when the coefficient of uniformity> or = 20.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Some rules for particle migration, filtering, and segregation were elaborated on the basis of some simple laboratory tests and data of well-designed, artificial mixtures of natural sand grains. Use was made of the knowledge available in the field and two pairs of grading entropy parameters. These parameters incorporate all information of the grading curve and are pseudo-metrics in the "space of the possible grading curves."

Download or read book Granular Materials written by Michael Sakellariou and published by BoD – Books on Demand. This book was released on 2017-09-06 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents basic notions and fundamental properties of granular materials covering a wide spectrum of granular material mechanics. The granular materials may behave as fluids or solids or both. The grain size may span from microscopic to macroscopic scale. From the wet sand effect, Reynolds inspired in 1885 the notion of granular universe introducing the term "dilatancy." Bak, Tan, and Wisenfeld (1987, 1988) used the sand pile as a representative model of complex systems. In this collection of chapters, granular dynamics, granular flow from dilute to jammed states, dynamics of granular gas in microgravity, particle jetting induced by impulsive loadings, particle migration phenomena in embankment dams, and the grading entropy-based criteria of granular materials and filters are presented.
