Abstract
Kako bi se postiglo poboljšanje svojstava tla koje će biti podloga građevini ili je samo potrebno povećati njegovu stabilnost, danas se najčešće koriti geosintetički proizvod -geomreža. Ovim diplomskim radom promatrati će se na koji način ugradnja geomreže utječe na uslojeni nekoherentni materijal, koliko daleko od ravnine ugradnje dopire utjecaj geomreže te na koji je način moguće usporediti energiju potrebnu za postizanjem željenog modula stišljivosti tako ojačanog materijala statičkim i dinamičkim postupkom zbijanja na terenu. Navedena pitanja biti će proučavana pomoć modelskih ispitivanja na modelima nekoherentnog tla ojačanog geomrežama u različitim razmacima ugradnje i različite veličine otvora na kojima će se mjeriti stupanj zbijenosti i modul stišljivosti. Prikazati će se također i rezultati kao i zaključci ranijih istraživanja na tu temu temeljem kojih se donosila odluka o odabiru inicijalnih vrijednosti za probna i početna ispitivanja. Modelsko istraživanje se provodi na slijedeći način: nekoherentan materijal i geosintetik se ugrađuju u pokusnu kutiju u slojevima koji se zbijaju, na površinu modela stavlja se kružna ploča s mikro-uricama koje bilježe slijeganja po obodu kružne ploče temeljem kojih se izračunava modul stišljivosti uzorka nakon prvog ciklusa opterećivanja (EV1) i modul stišljivosti uzorka nakon ponovljenog ciklusa opterećivanja (EV2).
Abstract (english)
In order to improve the properties of the soil that will be the foundation of the building or simply to increase its stability, the geosynthetic product - geogrid - is most often used today. This thesis will examine how the installation of the geogrid affects the layered incoherent material, how far from the installation plane the influence of the geogrid reaches, and how it is possible to compare the energy required to achieve the desired compressibility modulus of such reinforced material by static and dynamic compaction in the field. The above questions will be studied with the help of model tests on models of incoherent soil reinforced with geogrids at different installation intervals and different sizes of openings where the degree of compaction and compressibility modulus will be measured. The results as well as the conclusions of earlier research on the subject, based on which the decision was made to select the initial values for trial and initial tests, will also be presented. The model research is carried out in the following way: incoherent material and geosynthetics are installed in a test box in layers that are compacted, a circular plate with micro-grooves is placed on the surface of the model, which record settlements around the circumference of the circular plate, based on which the compressibility modulus of the sample is calculated after the first of loading cycles (EV1) and the compressibility modulus of the sample after repeated loading cycles (EV2).
