Characterization of the relationship soil density and simple compression resistance of silty soils

The unconfined compressive strength of soils is closely related to the shear strength that soil particles show in a material sample subjected to stress states where there are no lateral restrictions to stabilize the geotechnical structure. It is known that the resistance of a soil depends on its density and the type of soil. In engineering practice, it is highly desirable to have information in the form of empirical relationships that correlate readily and cheaply obtainable data for soil strength. This article presents an experimental study on materials subjected to compression without confinement and that leads to an empirical proposal that relates the density of a soil with the relationship it exhibits to simple compression.
