CHANGE OF A HIGHWAY ROUTE CAUSED BY A ROCKSLIDE

During the spring of 2013, a relatively large rockslide with a total area of 96,952 m(2) occurred in the eastern part of the Maid Fatra mountains. The anticipated depth of the slip surfaces was from 30 to 40 metres and the volume of moving mass was estimated to be 2,000,000 m(3). The maximum movement of the rockslide on the first day in March 2013 was estimated to be 43 m. The front of the rockslide interfered with the projected D1 highway route. The paper presented here offers an analysis of the causes of the rockslide and its activity in association with the potential threat to the proposed highway.
