Rockfall Analysis and Slope Stability Control of an Abandoned Marlstone Guarry in Majdan : Master's Thesis

U ovom radu izvršena je analiza odrona i kontrola stabilnosti kosine napuštenog tupinoloma u Majdanu. Preduvjet za korištenje tupinoloma u Majdanu kao rekreacijskog područja je stvaranje sigurnih uvjeta. S istočne strane tupinoloma strmi je zasjek visine do 50 metara sa prevjesom vapnenačkog pješčenjaka što predstavlja potencijalnu opasnost za korisnike rekreativne zone. Korištenjem matematičkih modela izvršen je proračun promjene geometrije lica kosine u vremenu. Za svaki vremenski korak napravljena je analiza odrona i kontrola stabilnosti kosine te su definirane mjere zaštite od potencijalnih odrona.In this paper an rockfall analysis and slope stability control of an abandoned quarry in flysch rock mass in Majdan was performed. A prerequisite for using quarry in Majdan as a recreational area is to ensure safe conditions. On the eastern side of the quarry is a steep slope up to 50 meters high with a large sandstone layers overhanging on the top which is a potential danger for future users of recreational area. Calculation and modeling of changes in the geometry of cuts in soft rock in time was made by using mathematical models. For each time step a two-dimensional model of the geometry of slope was made and simulations of the rockfall were performed. Based on the results of the above analysis, a measures of protection against potential odds were defined
