Fastness of biogenous soils

Abstract

On the basis of experimental data it is established, that the shearing strength increases proportionally to compressing load for all kinds of biogenous soils and silts. As the main volume of water being contained in water-saturated biogenous soils is bound and retained by organic soil component, the humidity of organic component can be accepted as a structural parameter that define fastness of these soils. For all kinds of biogenous soils and silts, enough close dependence of strength from humidity of organic component is established.
