Analiza aktywnego osuwiska i pełzania strefy przypowierzchniowej na zabudowanym Wzgórzu Chełm k. Bochni

A b s t r a c t.The paper discusses comprehensive stabilization solutions implemented in a settled, active/periodically active landslide area (SOPO ID number: 2833, 2841) on the north-eastern slope of Che³m Hill (boundary zone of the Outer Carpathians and the Carpathian Foredeep, Bochnia district).In addition to previously documented large-scale landslides, the slope has been affected for years by slow creep movements within the weathered material, which have had a negative impact on infrastructure and residential buildings.The applied geotechnical solutions -including drainage systems, retaining walls, and slope re-profiling -are presented as components of a coherent stabilization framework.Furthermore, the multi-aspect analysis incorporates satellite data from the Sentinel-1 programme, which enabled remote assessment of displacement rates over a longer time frame using radar interferometry (InSAR) techniques.The presentation of the geological engineering conditions also draws on data from inclinometer and piezometer measurements (surveys undertaken by PGI-NRI).The results allow for the assessment of the scale of dynamic hazards and their spatial and hydrodynamic conditions.They also generally indicate the effectiveness of the implemented solutions, while emphasizing the need for continued monitoring due to the active nature of the landslide.The proposed approach can provide a benchmark for comparable cases under similarly challenging geological settings.
