Abstract
Podzemna gradnja današnjice nameće sve veće zahtjeve u izvedbi. Bilo da se radi o cestovnom tunelu na autocesti izvan grada ili o tunelu u urbanoj sredini, projektiranje tunela smatra se izazovnim geotehničkim zadatkom. Prilikom projektiranja tunela nemoguće je osloniti se samo na jedan pristup zbog nepoznate sredine u kojoj se gradi. Najčešće se primjenjuju tri pristupa (empirijski, numerička analiza i opservacijska metoda) jednom rječju nazvana integralna metoda projektiranja. Cestovni tunel... More „Grič“, korišten je u ovom radu kao primjer za provedbu projektiranja iskopa i stabilizacije iskopa tunela prema tri pristupa. Empirijskim pristupom su dobiveni parametri stijenske mase, te prognozni podgradni sklopovi na temelju klasifikacija stijenske mase. Potom je provedena numerička analiza s empirijski usvojenim parametrima kako bi se dobila naponska i deformacijska stanja oko podzemnog otvora prilikom iskopa i podgrađivanja. Dobiveni su rezultati numeričke analize prihvatljivih vrijednosti, čime su se empirijske preporuke definirale kao konačno usvojene. Kako se radi o veličinama prognoznog karaktera, predviđa se program geotehničkog praćenja koji obuhvaća promatranja i mjerenja te se vrši verifikacija ili korekcija mjera stabilizacije. Less
Abstract (english)
Undergorund construction nowadays imposes huge requirements during the realization. Whether it is a road tunnel on a highway outside the city or a tunnel in an urban environment, tunnel design is considered a challenging geotechnical asignment. When designing a tunnel, it is impossible to rely on only one approach due to the unknown environment in which it is built. The most commonly used are three approaches (empirical, numerical analysis and observational method) in one word called the... More integral design method. The road tunnel "Grič" was used in this paper as an example for the implementation of excavation design and stabilization of tunnel excavation according to three approaches. The parameters of the rock mass and prognostic support systems based on rock mass classifications were obtained by empirical approach. Then numerical analysis with empirically adopted parameters was performed to obtain stress and strain states around the underground opening during excavation and support instalation. The results of the numerical analysis were acceptable values , so the empirical recommendations were defined as final.Sincethese are prognostic quantities, a geotechnical monitoring program, which includes observations and measurementsis planned. If necessary, verification or correction of the support system is performed. Less
