Abstract

Ovaj diplomski rad bavi se analizom graničnog stanja uporabivosti temeljnog sustava objekta Hrvatskog muzeja arhitekture. Dani su opći i tehnički podaci o građevini kao i o temeljnom tlu na kojem se građevina nalazi. Vizualnim pregledom muzeja uočene su pukotine koje ukazuju na diferencijalna slijeganja objekta, nastale najvjerojatnije uslijed neadekvatne drenaže oko objekta, te potrebu za sanacijom istog. Iz tog razloga su u programu GGU Slab napravljeni numerički modeli, kojima su prikazane vrijednosti slijeganja temeljnog tla. Prikazane su moguće metode sanacije te je napravljen numerički model koji prikazuje predviđena slijeganja nakon izvedbe sanacije odabranom metodom, a to je jednofluidna metoda mlaznog injektiranja. Ovom metodom se poboljšavaju fizikalno-mehaničke karakteristike tla i sprječava se daljnje ispiranje tla koje je za posljedicu imalo pojavu diferencijalnih slijeganja. U radu je opisan i postupak izvođenja sanacije te je dan prijedlog detaljnih geotehničkih istražnih radova koje je potrebno provesti prije početka sanacije.

Abstract (english)

This thesis analyses the serviceability limit state of foundation system of 'Croatian Museum of Architecture' building. General and technical information of the building are given as well as the information about the soil on which the building is located. Visual inspection of the museum revealed cracks indicating the differential settlement of the building, most probably from non-adeqaute drainage around the building, and the need for remediation is stressed-out. For this reason, numerical models have been made in GGU Slab which show the values of the settlements of the soil. Possible remediation methods are presented and a model, that shows the predicted settlements after the remediation, is made. The selected method of remediation is a single-fluid jet grouting method that improves soil physical-mechanical properties and prevents further soil washing, which has resulted in differential settlements. This thesis also describes the procedure of remediation. At last, a detalied geotechnical exploration work suggestion is given and must be carried out before the remediation begins.
