    Opis:
    Landslide recognition is an important task for designers and contractors during the road construction process. The problems that contractors often face is insufficient recognition of the geological structure (at the design stage), too small area of purchased land under the "ZRiD’'decision, or the inability of fast responding to emerging threats. The studies described in this article shed more light on the complexity of slope deformation as a result of landslide processes. During the constructing of the expressway S-7, the problems related to deep landslide processes occurred, which most probably were associated with poorly recognized old “rocky-weathering material” type of landslide. The geological survey performed during the construction of this road, confirmed the occurrence of deep (>20 m) displacements, recorded by the inclinometer measurements. These deep displacements are linked to a large landslide with a main scarp located in the region of Mt. Cymbalowa Góra.

    Opis:
    The area of Poland, including the Carpathian Mountains, is located in a zone where landslides cause large material damage. This issue can be considered using different time scales. Using various dating methods, it was possible to distinguish periods of increased landslide activity. Among others, the radiometric methods are the most common. Based on the 14C dated landslides in Szczawnica-Biafy Stream, Zapadle near Szymbark, Rychwatd near Żywiec and on data published by Margielewski (2006), it was possible to hypothesize that landslides in the Carpathians have been developing over 13,000 years, i.e. since the Oldest Dryas. This is related to the beginning of degradation of the permafrost, which can be considered as the inception of the development of large rock landslides. On the basis of the presented data, it can also be stated that these landslides have been active up to modern times and their development is very long. An example of this is the landslide in Zapadle. The position of the landslide tongue, which is subjected to erosion, is of great importance, which promotes its further activity. Permanent removing of the colluvial material by a stream and its supplementing by subsequent new displacements from the scarp causes that the landslides can be active for a very long period of time.

    Opis:
    When conducting geological and engineering research, the most common statement is information that the landslide is shallow and should not pose a threat to the designed objects. In the case of large, structural landslides, this approach may lead, with the wrong determination of the deepest slip surface, to the occurrence of a construction disaster as a result of improper execution of the protection structure. The article presents specific locations of landslides with deep displacements in inclinometric columns exemplified by landslides monitored as part of the SOPO project in Tarnawa Górna, Słotowa and Międzybrodzie Bialskie - Łazki. The documented slip surfaces are found at depths of 19-42 m. Such deep displacements indicate that large, landslides reach significant thicknesses and such data should be presented in a geological and engineering documentation. It is proposed to modify the regulation on the execution of the geological and engineering documentation by adding a point regarding the documentation of landslides. If such an area exists, special requirements must be met when conducting geological surveys.

    Opis:
    When conducting geological surveys in landslide areas, it is important to define the scope of the planned geological works. The most important issue in the study of landslides is the recognition of the depth and shape of the slip surface. This requires the correct type of drilling and a good core quality. Most often, within a single landslide, several slip surfaces are documented, which occur at different depths, which is associated with a complex manner of motion and shear. Proper determination of the deepest sliding surfaces allows for the construction of a calculation model and selection of the optimal method of securing the landslide area. The course of the slip surface is often not determined by the depth of the bedrock under the cover formations. Geological diagnosis should depend on the size of the examined landslide and the impact of its activation on potential damage / destruction of existing buildings and technical infrastructure. The method of documenting and carrying out calculations is presented as recommended in landslide areas. In the first step, calculations should be made on the basis of data obtained from field work and parameters obtained from laboratory tests. Monitoring should complement field research and assess the scale of displacements. Conducting stability calculations should be a standard for the preparation of geological and engineering documentation of landslides and areas at risk of mass movements. It allows you to assess the risk and threats to the planned investment or protective structure. This is to provide permanent safeguards to prevent damage to buildings that have been designed on the basis of uncertain geological data. It is postulated to modify the ordinance on the implementation of geological and engineering documentation by adding a point concerning the documentation of landslides. If there is such an area, special requirements must be met when conducting geological surveys.

    Opis:
    Theintensification of disastrous landslide movements in southern Poland occurring at the end of the 20th century, showed that there was a need to create a unified system of acquiring and collecting landslide data. It also indicated the importance of raising awareness of the existence of landslide hazard for both residents and public administration (decision-makers). This was also the reason for launching a nationwide project, the Landslide Counteracting System (LCS; SOPO in Polish). This system is a platform for acquiring and processing information about mass movements in order to support mainly for government and local administration. The main goal of the project is to reduce the landslide riskin Poland,and to limit damages caused by the development of landslides.
