The rheological approach in an assessment of interparticle interactions in soils

[摘要] The rheological parameters were determined by the amplitude sweep test on the MCR-302 rheometer and have shown a behavior specificity of soils of different genesis depending on a texture and organic matter content. Light loamy gley podzolic soils of the northern taiga have a dilatant hardening of interparticle bonds, but their stability is extremely low. Soddy-podzolic soils of the Moscow region have somewhat greater stability, and it is similar to a gley podzolic soils' stability. The typical chernozem has the greatest stability to stresses.
