In order to study in depth the impact of vibration
on the strength characteristics of clay soils, as well as to
develop methods that increase the strength characteristics and
contribute to the elimination of seismic shrinkage deformations
of clay soils, we conducted research in the field. In field
experimental studies, the svaw-12 trailed, smooth vibration
roller, manufactured in Germany, was used. We paid special
attention to the further behavior of the soil after the vibration
and made observations and measurements of soil indicators for
two months. The experiments in the field with vibration column
showed an increase of soil deformation with increasing
duration of the fluctuations, i.e. there is a linear relationship
between the increases in soil density on the duration of
oscillations. In the process of vibration, there is a sharp
decrease in the force of adhesion and the angle of internal
friction, which is apparently associated with a violation of the
structure of the soil and its compaction. And then at the end of
the vibration process, over time, there is an increase in the
adhesion (1.5-2 times) and the internal friction angle (1.2
times) of the soil, obviously as a result of the soil acquiring new
strength and compaction under the influence of its own weight.
This circumstance is also associated with the humidity state of
the soil.
