dc.description.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. en_US
dc.description.abstract Lucrarea prezintă, în sinteză, rezultatele cercetărilor privind metodele experimentale de stabilizare a solului cu substanţe ecologice pentru a realiza unele structuri stabile și durabile folosind procese tehnologice de compactare prin vibraţii. Pe baza testelor de laborator și „in situ”, s-au stabilit valori ale elasticităţii solului, luând în considerare modificarea coeficientului Poisson. Drept urmare a modificării dimensiunii și conţinutului porilor enzimatici în procesul de tratare atomizată a solului prin amestecare specială se produc variaţii semnificative ale modulelor de elasticitate (monoaxial și în volum), iar coeficientul de rigiditate variază în direcţia normală a vibraţiei la suprafaţa de compactare a solului. Efectul stabilizării solurilor instabile pe baza soluţiilor enzimatice este și mai semnificativ pe măsură ce indicele de porozitate scade, raportul Poisson și modulul de elasticitate al solului este în creștere. ro
