FIZIČKO MODELIRANJE UTJECAJA PILOTSKE STIJENE NA STABILNOST GLINOVITE PADINE USLIJED DJELOVANJA OBORINA

The small-scale physical model platform was developed as part of a four-year research project, "Physical modeling of landslide remediation constructions' behaviour under static and seismic actions, " to investigate the behaviour of slopes built of different materials with and without remedial measures under the influence of rainfall and earthquake. As in real landslides, the observation of a physical model consisted of a geotechnical and a geodetic monitoring system. In this paper, the behaviour of clay-like slopes during 1g artificial rainfall, with and without remedial measures will be described. Complex remedial measures included deep trench drains which reduced pore water pressure, and pile wall with head beam made with 3D printer, which increased shear resistance at the sliding surface. At the same rainfall intensities, the clay-like slope collapsed, while the slope supported with a pile wall at the slope foot remained stable. The results of the photogrammetric equipment and the complex sensor network measurements within a slope are presented and discussed, helping us to understand the different behaviour of slopes with and without remedial measures.
