Abstract

U radu se razmatraju geotehničke analize desnoobalnog nasipa rijeke Gline oštećenog u potresu koji je pogodio Sisačko-moslavačku županiju u prosincu 2020. godine. U prvom dijelu rada definiran je pojam likvefakcije te su navedene su glavne aktivnosti kojima će se sanacije oštećenog nasipa. U nastavku slijedi pregled istražnih radova izvedenih na predmetnoj lokaciji, razrada podloga i odabir relevantnih parametara tla. Kroz tekstualne formulacije, grafičke prikaze te jednadžbe prikazani su geotehnički proračuni. Rađene su analize procjeđivanja i analize stabilnosti predmetnog nasipa prije i poslije sanacije oštećenja primjenom programskog paketa GeoStudio. Rezultati analiza su pokazali zadovoljavajuće vrijednosti hidrauličkih gradijenata i faktora sigurnosti čime je potvrđena uspješnost sanacije pokosa nasipa zasijecanjem uz zamjenu materijala i ugradnjom geomreža, uz ojačanje temeljnog tla mlaznim injektiranjem.

Abstract (english)

The thesis deals with the geotechnical analysis of the right-bank levee of the Glina river damaged in the earthquake that hit Sisačko-Moslavačka county in December of 2020. In the first part of the thesis, the concept of liquefaction is defined, as well as the main activities that will be conducted to rehabilitate the damaged levee. An overview of the investigation works carried out follows, as well the selection of the relevant soil parameters. Through text, graphics and equations, geotechnical calculations are presented. Analysis of water seepage and analysis of levee stability are evaluated before and after the rehabilitation measures, and were carried out using the GeoStudio software package. The results of the analysis show satisfactory values of hydraulic gradients and safety factors, which confirmes the success of the levee rehabilitation by replacement of materials and installation of geosynthetics, along with foundation soil strengthening by jet grouting.
