Numerical approach to soll material classification

摘要: Abstract A numerical method was created and used to objectively reproducibly establish the soil material classes. Fifty six soils were sampled on west slope of Mt. Oye in Kaya Township, Kyoto Prefecture. Seventeen field laboratory attributes selected so that they would coincide with those employed by a surveyor for c1assifying sampIes conventional way. Hayashi's theory quantification No. 3 (Hayashi 3), which quantifies similarity between any pair individuals based their “response pattern” each variables concerned, introduced assess relationship respect c1assitication. Each sample plotted taking its scores derived from Hayashi analysis as coordinates scattergram, four clusters c1early separated one another. These corresponded following types distinguished surveyor; serpentinie material, mixed serpentine g...
