ENGINEERING GEOLOGICAL CHARACTERISTICS OF THE ROAD SOLIN - KLIS (DALMATIA, CROATIA)

Istraživanjima u »intaktnom« terenu, kao i na izvedenim kosinama usjeka i zasjeka, u temeljnim jamama objekata i u tunelima, određene su inženjerskogeološke i osnovne tektonske značajke senonskih vapnenaca, eocenskog fliša, prominskih breča i brečo-konglomerata, te oligocenskih slabo sortiranih breča, na trasi poluautoceste Solin-Klis (Dalmacija, Hrvatska). Laboratorijskim ispitivanjima na velikom broju uzoraka stijena utvrđeni su rasponi njihovih osnovnih fizikalnih i mehaničkih značajki unutar pojedinih inženjerskogeoloških cjelina. Rezultati laboratorijskih ispitivanja uspoređeni su sa svojstvima stijenskih masa u cjelini procijenjenim primjenom RMR-klasiflkacije stijena i rezultata mjerenja brzine širenja uzdužnih seizmičkih valova. Ukazano je na mogući istovjetan pristup i kod izrade Osnovne inženjerskogeološke karte Republike Hrvatske.The research, that has been done both on the »intact« terrain and on the opened cuts and discontinuities, and which has been carried on in the basic caves of the object, as well as in the tunnels; has verified the engineering geological and basic tectonic characteristics of Senonian limestones, Eocene flysch, the Promina breccias and breccia-conglomerates, as well as Oligocene poorly sorted breccias, on the route of semi-highway Solin-Klis (Dalmatia, Croatia). The lab analyses, of the great number of the rock samples, have brought out the parametres of their basic physical and mechanical features within a particular engineering geological unit. The results, thus obtained, have been compared to the qualities of the rock structure block as a whole, and had been previously evaluated by applying RMR-classification of the rocks, and the results of the measured velocities of the longitudinal waves. It has been pointed out that similar procedure may be applied in the publication of General Engineering Geological Map of the Republic of Croatia
