EXAMPLES OF LANSLIDES IN THE FEDERATION OF BOSNIA AND HERZEGOVINA WITH THE ANALYSIS OF THE CAUSES OF THEIR ACTIVATION

Abstract

Bosnia and Herzegovinais characterized by heterogeneous geological structure, and a high degree of tectonic and the seismic activity as well as various relief and the climatic characteristics and water flows of different gradients. All this reflected on engineering-geological characteristics of the terrain.

The main causes of landslides' activation are changes in level of underground waters, chopping down of forest, great rainfalls, snow melting, long drought periods, changes in slopes, changes in load of a slope, rock's wastage, uncontrolled diversion of surface waters, earthquakes etc. Researches on landslides are carried out in order to establish the cause of landslide's origin and to find out efficient overhaul measures. Landslide's overhaul success depends not only on established causes of landslide's origin, but also on use of technical measures for stopping that process. Overhaul measures' carrying out is important in protection of the environment.

This paper presents an analysis of co-action of natural factors and negative anthropogenic effect in a settled area, where landslides appear, by its studying and eliminating of causes we are creating the conditions for a successful stabilization of landslides. The paper shows some characteristic landslides with defining of geomorphologic, geologic, engineer geologic, hydrogeologic and geotechnical characteristics of the terrain.
