Zabezpieczenie osuwisk to istotny proces mający na celu zapobieganie lub minimalizowanie niebezpieczeństwa wynikającego z ruchów masowych terenu. Istnieje kilka sposobów zabezpieczenia osuwisk, które mogą być stosowane w zależności od charakterystyki konkretnego osuwiska oraz jego otoczenia.

W artykule przedstawiono doświadczenia ze stabilizacji osuwiska na historycznym wzgórzu Rotunda w Krzeszowie. Zabezpieczenie polegało na wykonaniu metodami geoinżynieryjnymi bloków gruntowo-cementowych o określonych kształcie i rozmiarach, pełniących funkcję sztywnych przypór w zboczu osuwiskowym. Przeprowadzono szczegółową analizę obliczeniową stateczności zagrożonego terenu i zaproponowano optymalny sposób zabezpieczenia z wykorzystaniem technologii wgłębnego mieszania gruntu (DSM). Układ i konstrukcję przypór z paneli DSM przyjęto według autorskiego projektu stabilizacji osuwiska. Po zakończeniu prac stabilizacyjnych historyczne wzgórze Rotunda zachowało niezmienione formę i kształt.

The article describes experiences from the stabilization of landslide on the historic Rotunda hill in Krzeszów. The method consisted in the fabrication of ground and cement blocks, used as the rigid supports of the slope. The calculation analysis of stability was carried out and the optimum method of protection by the Deep Soil Mixing (DSM) technology was applied. The arrangement and construction of DSM panels was adopted according to the authors’ project of landslide stabilization. After the stabilization works had been completed, the historical Rotunda hill retained its form and shape.

The objective of this paper is to presents results and conclusions from landslide monitoring and early warning methods implemented by the author for road and infrastructure stabilization projects. Research present monitoring for 23 Carpathian landslides and 8 counteraction projects. Implemented instrumentation besides standard monitoring methods included automatic on-line measurements with real-time transfer of landslide data to the Internet. The initial site investigations were funded under the Landslide Counteraction Project (2005–2009). Standard monitoring measurements was financed by author and Poltegor-Institute (2006–2015). Real-time measurements were realized inside the EU Innovative Economy Programme (2008–2013). These measurements are conducted and financed by the author till now. The instrumentation consists of 26 standard inclinometers to depths of 5–21 m. Up to Fifty five series of measurements performed 4–9 times a year from 2006 till now detected displacement from several millimetres to 49 cm. These were observed at depths of 1–17 m. Modern automatic, early warning, real time system was installed in May 2010. The system is the first of its kind in Poland and one of several such a systems in the world. The installation was carried out in consultation with the Local Road Authority in Gorlice. It contained three automatic field stations investigating landslide parameters to the depths of 12–16 m and the weather station. The displacements were measured by in-place inclinometers, and innovative 3D continuous inclinometer systems with sensors located every 0.5 m. It has possibility to measure much greater range of movements compare to the standard systems. The obtained data allowed better recognition of geohazards triggering parameters and control of landslide stabilization works. It included definition of risk conditions. The early-warning about the risk to the road owner and the Carpathian Branch of Polish Geological Survey were implemented. Chosen monitoring methods and numerical modelling could help in forecasting of the landslide movement for estimation of remediation possibilities and improve effectiveness of stabilization works. However, landslide stabilization works are usully difficult and should be connected with control monitoring measurements.
