Abstract
Nakon potresa magnitude 6.4, koji se dogodio 29. prosinca 2020. godine s epicentrom u Petrinji pojavilo se preko 100 pokrovno-urušnih vrtača na površini od približno 1 km2 tijekom nekoliko mjeseci od potresa. Geotehnički istražni radovi na promatranom području izvedeni su početkom 2021. godine. Analizirani su postojeći geološki i hidrogeološki podaci te su zabilježene geometrije vrtača. U blizini najveće vrtače, koja se nalazila u Mečenčanima, izvedene su dvije istražne bušotine s kontinuiranim jezgrovanjem. U istim bušotinama izveden je standardni penetracijski pokus. Naknadno su izvedena i laboratorijska ispitivanja fizikalnih, indeksnih i projektnih svojstava tla. Modeliran je karakterističan profil tla, za najveću vrtaču, koji je korišten za numeričke analize kako bi se ispitali mogući mehanizmi loma te izvršile parametarske analize radi utvrđivanja ovisnosti utjecaja geometrije i stanja naprezanja na nastanak pokrovno-urušnih vrtača.
Abstract (english)
After the magnitude 6.4 earthquake that occurred on December 29, 2020, with its epicentre in Petrinja, more than 100 cover-collapse sinkholes appeared over an area of approximately 1 km2 in the months following the earthquake. Geotechnical site investigations were carried out in the area affected by the earthquake in early 2021. Existing geological and hydrogeological data were analysed, and the geometries of the sinkholes were recorded. Two exploratory drillings with core sampling were conducted near the largest sinkhole, located in the Mečenčani village. Standard penetration tests were performed in the same boreholes. Subsequently, laboratory tests of physical, index, and engineering properties were conducted. A typical soil profile was modelled for the largest sinkhole, which was used for numerical analyses to investigate potential failure mechanisms and perform parametric analyses to determine the dependencies of the influence of geometry and stress conditions on the formation of cover-collapse sinkholes.
