Application of geophysical methods in the study of landslides

摘要

The paper discusses the results of the study of landslide processes by geophysical methods. In examining of landslides it is important to find out the features of their structure but it should always remember that landslides, as a rule, have the various combination of contrasted boundaries sometimes with a high gradient of physical properties. Analysis of landslide blocks various types suggests that it is not always possible to obtain reliable and sufficient information using just one geophysical parameter. Therefore, to study landslides, it is expedient to use a set of geophysical methods and to determine complex indicators. The study of landslide processes is one of the most difficult tasks for engineering geophysics, because the researches must be performed on rather steep slopes with physical heterogeneous of slip area. Size of study area (commonly used a lateral lengths of landslide) is usually limited, which the standard geophysical methods had thereby been m ade more difficult. In this paper there is an example, we present some results of geophysical studies performed in the district of Vytachiv. Geophysical methods are proved to be efficient for studying landslides.
