Long range bonds are found in clay mineral systems and allow the occurrence of plasticity. They are represented by c in the standard Coulomb equation. Short range bonds are found in inactive particle systems. These are soil systems where the constituent particles do not have a significant ...
The clay dikes were found to be associated with thin coal along crests and adjacen... WB Wilson 被引量: 0发表: 1916年 TIME EFFECTS AND PROGRESSIVE FAILURE IN CLAY SLOPES The stability of over consolidated fissured clays and clay shales is a central problem in Soil Mechanics. In this ...
some influences of soil intrinsic factors(soil types,organic matter,clay,pH, Eh and CEC,etc),and some external factors affecting soil environment(geographical area,temperature,water or moisture,fertilizer application or agricultural measures,etc),are the most challenging fundamental problems of soil-...
The construction of extruding\|soil piles has an obvious extruding\|soil effect, which can initiate other severe environmental problems. In this article, authors conclude 8 measures to prevent and cure these environmental problems, and point out that adoption of prevention and cure measures should be...
where pH values in polluted soil will be adjusted by clay minerals and contents of the ammonia nitrogen and the sulfate radical will be decreased.All soil removed from other place adding restoration materials will be filled in ecological bags and assembled on the exposed land of rare earth mine...
The poroelastic soil medium obeys the Vardoulakis-Beskos theory, while the poroelastic, fissured rock medium the Aifantis-Beskos theory. The quasi-static counterparts of these problems are analysed as special cases of the dynamic ones. Use of Laplace transform with respect to time reduces the ...
摘要: This paper provides an insight on the role of interplay between physical and numerical models for soil structural interaction problems. The relevant points are illustrated using the results of studies on deep excavation in soft clay and gravity caisson sand....
Plant regeneration from seed in arid calcareous silty clay rangelands was better when protected from grazing; it was very slow due to surface crusting, low soil moisture content and high soil temperature which prevailed most parts of the year. Contour planting with water harvesting are possible ...
