Važnu ulogu kod izbora metode iskopa ima numeričko modeliranje otvora u stijenskom masivu na osnovi geotehničkih podataka dobivenih terenskim i laboratorijskim ispitivanjima. Napravljene su analize stanja naprezanja i deformacija iskopa tunela s m

Placed in urban area of coastal town Opatija, underground structure is designed with large cross-section of 205-220 m2 and total length of 30 m. Maximum overburden is only 11 m. Entire project is one of the most challenging tasks at underground works

U radu su na primjerima izvedenih portalnih dionica tunela (građenih u razdoblju od 2006. do 2009. godine) napravljene usporedbe terenskih mjerenja konvergencija u tunelu i slijeganja površine terena s rezultatima numeričkih proračuna. Numeričke

A spherical cavity appears after blasting of certain quantity of explosive at the bottom of a borehole in clay or soft rock. An anchor or bolt is inserted in the cavity, and the cavity and borehole filled up with concrete, mortar or grout mix. The an

U širem smislu rudarstvo obuhvaća radove iskopa i podgrađivanja podzemnih prostorija. Iskopi u slabim materijalima pri proboju trasa autocesta uvjetuju razradu profila, tj. primjenu višefaznih iskopa. Predviđanje ponašanja stijenskog masiva tij

Tunnell excavation by drill+blast is often limited when the new tunnels have to be excavated close to the existing tunnels in traffic, or in urban areas. Controlled blasting with constant seismic monitoring can be applied very efficiently with good a

Predviđanje odziva stijenskog masiva prilikom proboja tunela složen je inženjerski problem. Pri projektiranju važno je ocjenjivanje uvjeta stabilnosti iskopa, te nakon usvajanja prikladnih metoda probijanja, usvajanje odgovarajućih mjera podgra

U tunelogradnji razlikujemo tunelogradnju u čvrstim stijenama i tunelogradnju u slabim stijenama ili tlu. Nove teorije i pristupi tunelogradnji omogućile su razvoj modernih metoda iskopa u slabim stijenama. U našim je uvjetima zbog svojih tehničk
