ASPECTS REGARDING EVALUATION OF COMPACTING PROCESS BY VIBRATION OF ENZYME-STABILIZED SOILS

Abstract

The paper presents, in synthesis, the outcomes of the research on the experimental methods of soil stabilization with ecological substances in order to achieve some stable and durable structures using technological processes of compacting by vibration. Based on laboratory and „in situ” tests, there were determined values of soil elasticity taking into account Poisson's coefficient change. Thus, as a result of the modification of the size and content of the enzyme pores in the process of atomized treatment of the soil treated by special mixing, significant variations of the elasticity modules (monoaxial and volume) are produced and of the stiffness coefficient varies in the normal direction of vibration at the soil compaction surface. The effect of unstable soils stabilization using enzymatic solutions is even more significant as the porosity index decreases, Poisson's ratio and the modulus of soil elasticity is increasing.
