Abstract
U ovom radu opisane su mehaniĉke i fiziĉke znaĉajke razliĉitih ĉlanova flišne stijenske mase. Provedena su laboratorijska i terenska ispitivanja na podruĉju sjeverne Istre kako bi se na osnovu dobivenih rezultata bolje razumjele karakteristike mekih stijena, ali i ukazalo na pouzdanost odreĊene metode ispitivanja vrlo sloţenog materijala kao što je fliš. Od terenskih ispitivanja provedena je procjena stupnja trošnosti stijenske mase u podnoţju Uĉke i dobiveno je da prevladavaju stupnjevi veće trošnosti. Na terenu su provedena i ispitivanja jednoosne tlaĉne ĉvrstoće pomoću geološkog i Schmidtovog ĉekića, dok je u laboratoriju proveden pokus opterećenja u toĉki (PLT metoda). Ispitivani su vapnenci, siltiti te pješĉenjaci, a dobiveni rezultati razlikuju se ovisno o primjenjivanoj metodi. U vrijednostima ĉvrstoće koje su dobivene pomoću Schmidtovog ĉekića prevladavaju manje vrijednosti od vrijednosti ĉvrstoće dobivene pokusom opterećenja u toĉki. Poznato je da je PLT pokus pouzdaniji te ukoliko se provodi na pravilan naĉin, propisan standardom moţe dati valjane rezultate. Prilikom ispitivanja Schmidtovim ĉekićem jednostavno se doĊe do pogreške zbog znaĉajki površine materijala stijene koja se ispituje te orijentacije ĉekića, odnosno sveukupnog naĉina njegovog korištenja.
Abstract (english)
This paper describes the mechanical and physical characteristics of the various members of the flysch rock mass. Laboratory and field tests were performed in the area of northern Istria in order to better understand the characteristics of soft rocks on the basis of the obtained results, as well as to indicate the reliability of a particular testing method for very complex material such as flysch. During field testing, an assessment of the rock mass weathering degree, at the foot of Uĉka mountain was performed and higher degrees of weathering were obtained. In the field, uniaxial compressive strength tests were carried out using a geological and Schmidt hammer, while a Point Load Test was performed in the laboratory (PLT method). Limestone, siltstone and sandstone were tested, and the obtained results differ depending on the used method. The strength values obtained with Schmidt hammer outweigh the smaller values than the strength obtained by the Point Load Test. It is known that the PLT experiment is more reliable and, if carried out properly, prescribed by the standard can give valid results. When tested with Schmidt hammer, an error simply occurs due to the surface characteristics of the rock material being tested and the orientation of the hammer, or the overall method application.
