The paper presents the possibility of using complex geophysical investigations and geotechnical classification to identify geological structure and assess the stability of Carpathian landslides. The possibility of using seismic surveys to determine the landslide slope geometry necessary to analyze the computational stability has been indicated. In the paper authors present the possibility of geotechnical classification of the flysch KFG basis on the geophysical parameters in connection with the SMR classification proposed by M. Romana, for a rapid quantitative assessment of flysch slope stability. Examples of geophysical investigation of landslides and their stability are described on the basis of the KFG and SMR classification. The proper slope stability assessment has been pointed out as a major factor contributing to safe foundation and operation of engineering structures, especially hydrotechnical structure.

The article discusses the slope stability of retaining walls made of small-dimensional concrete blocks and geosynthetics. It presents an insight into the issue based on two examples with different soil conditions and methods which can be used to mitigate the risk of failure of reinforced soil structures.

W artykule przedstawiono problem ochrony skarp związany z postępującą urbanizacją terenu. Ocena warunków geotechnicznych w przypadku zabudowy terenu wymaga dokumentacji badań podłoża, a przy trzeciej kategorii geotechnicznej również badań geologiczno-inżynierskich wraz z projektem geotechnicznym. Przedstawiony przypadek powstania osuwiska wskazuje na konieczność analizy wstecz zmian w ukształtowaniu terenu, przebiegu zmian kierunków spływu wód opadowych i gruntowych tak daleko jak to możliwe. Historia zmian w podłożu to zwykle kilkaset lat i ma zawsze istotne znaczenie dla ochrony obszarów przyskarpowych.

The paper presents slope protection problem related to urbanization process. Evaluation of geotechnical conditions for the subsequent stages of development, requires ground investigation report and, for the third geotechnical category, engineering-geological documentation with the geotechnical project. Presented case of landslide creation indicates a need of back analysis of changes in the terrain morphology, rainwater and groundwater flow direction changes as far as possible. History of changes in the substrate is usually several hundred years, and for the protection of near slope areas is always important.

Localised landslide activity has been observed in the area of the plateau slope analysed, in the vicinity of the planned Warsaw Southern Ring Road. Using calculation models quantitative and qualitative evaluations of the impact of natural and anthropogenic load factors on slope stability (and hence, safety) are made. The present paper defines six stages of slope stability analysis, leading to an indication of optimum slope design in relation to the development planned. The proposed procedure produces a ranking of factors that affect slope stability. In the engineering geological conditions under consideration, the greatest factors impacting degradation and failure of slope stability are changes in soil strength due to local, periodic yielding and the presence of dynamic loads generated by intensification of road traffic. Calculation models were used to assess the impact of destabilisation factors and to obtain mutual equivalence with 3D-visualisation relations. Based on this methodology, various scenarios dedicated to specific engineering geological conditions can be developed and rapid stability evaluations of changing slope loads can be performed.
