The suggested transfer function construction method - based on a double approximation technique, the grading entropy concept and at most quadratic many data in terms of the fraction number – is tested on the example of the dry density of sands here using some previously measured data. In the first approximation step a “preliminary transfer function” is interpolated in the nonnormalized grading entropy diagram on the basis of some “optimal” soil data. In the second approximation step the preliminary transfer function is extended to the space of the possible grading curves with the constant function. The so determined transfer function is tested against an independent “non-optimal” data set, measured on some soil series with basically continuous (i.e., not gap-graded) grading curves. The aim of this paper is to present the main results of the study supporting the goodness of the method and the predictability of the dry density transfer function. 2011-06-30T04:40:03.437Z ]]> A general density law for sands http://nova.newcastle.edu.au/vital/access/manager/Repository/uon:6247 A new transfer function generation method was applied in the simplest form to find the relationship between the grading curve and the dry density. The method is based on the grading entropy concept. Some laboratory emax test data were made for the generation of a preliminary dry density transfer function using “optimal” soils. The goodness of results was tested on the basis of an independent data set related to some “non-optimal” soils mixtures. The agreement between the two preliminary transfer functions was surprisingly good. The measured data were evaluated with respect to the densest packing problem. 2010-05-12T04:40:02.933Z ]]>
