| dc.description.abstract | The paper deals with the slide of Doubrava Vrchovec that occurs in district of Karviná in Doubrava Village. The slope deformation in this area was reactivated by mining effects and by precipitation. The studied area is the Ostrava-Karviná coalfield, situated in the Northeast of the Czech Republic. Objective area is situated in efficient distance of mining activity of both mining fields. Great movements temporally correlate with mining of most thick seams of Mine Doubrava and Mine CSA. Archive materials, basic data, aerial photographs of slope deformation were studied and evaluated at the beginning of the research. Moreover, engineering-geological mapping were performed, on the basis of which all landslide manifestations, such as starting scar, transport zone, accumulation area, cracks, sliding blocks, side banks, layer outcrops, hydrogeological structures (for example, wells, wetlands, springs, line of springs). Resistivity tomography measurements (geophysical method of multielectrode resistivity measurement) were taken. On the basis of the carried out exploration work, it can be said that the manifestation of sliding activities have been clearly proved. The stability can be considerably affected by heavy rainfall due to their degradation effects on the mechanical properties of soils. More intense effects of rainfall are also caused by the existence of tension cracks that occur in the slide. These discontinuities substantially weaken the slope, facilitate the seepage of rainfall and can possibly lead to the formation of other partial slides. © 2011 Academic Journals. | en_US |
