Abstract	Tijekom i nakon potresa 29. prosinca 2020.godine u Petrinji, osim uobičajenih pojava zapažen je veliki broj urušnih vrtača. Urušne vrtače nastaju ispiranjem materijala iz pokrova pri čemu on gubi čvrstoću i dolazi do urušavanja. Pregledom terena zabilježeno je 45 postojećih, 91 novonastalih i 3 potencijalne vrtače. S obzirom da je ta pojava rijetka i u svijetu, provedena su brojna geološka, hidrogeološka, geofizička i geotehnička ispitivanja, te su uzeti uzorci tla za laboratorijsko ispitivanje. Uzorci su dobiveni rotacijskom ručnom bušilicom te uzorkovanjem pomoću cilindra. Za ispitivanja prikazana u ovom radu odabrani su uzorci tla izvađeni iz bušotina izvedenih pored dvije karakteristične vrtače u naselju Borojevići. Na odabranim uzorcima provedena je terenska identifikacija i klasifikacija koja je naknadno nadopunjena laboratorijskim pokusima. Osim toga, provedeno je ispitivanje mehaničkih i hidrauličkih značajki pokrovnih naslaga. U ovom radu detaljno je opisan postupak određivanja posmične čvrstoće pokusom izravnog smicanja te su analizirani rezultati ispitivanja.
Abstract (english)	During and after the earthquake that occurred on 29th December 2020 in Petrinja, apart from the usual occurrences, a large number of cover-collapse sinkholes have appeared. Cover-collapse sinkholes appear due to washing out materials from the cover in a way that it loses strength and collapses. During the inspectoion of the area, 45 existing, 91 newly-formed and 3 potential sinkholes have been recorded. Considering that this phenomenon is very rare worldwide, numerous geological, hydrogeological, geophysical and geotehnical investigations have been conducted, and soil samples for laboratoty tests have been taken. The samples were obtained with a portable rotary power auger and by using a sampling cylinder. For the research presented in this paper, representative soil samples were obtained from the boreholes drilled next to two typical sinkholes in the village of Borojevići. Field identification and classification have been done on the chosen samples, and this has been complemented with laboratory tests. In addition, testing of the mechanical and hydraulic characteristics of the cover deposits has been conducted. This paper brings a detailed procedure of determining the shear strength with the direct shear test, as well as the analysis of the test research results.
