Sažetak
Physical modelling of landslides using scaled landslide models behavior began at the end of 1980s when behavior of flow slides and liquefaction of sliding materials were investigated in a scaled physical model (so called flume or flume test). The main purpose of landslide physical modelling in the last 25 years was research of initiation, motion and accumulation of fast flow like landslides caused by infiltration of water in a slope. Existing studies of landslide remedial constructions’ behavior using physical modelling are very rare. In October 2018, at the Faculty of Civil Engineering, University of Rijeka, started a four-year research Project Physical modelling of landslide remediation constructions’ behavior under static and seismic actions, funded by the Croatian Science Foundation. The main Project aim is modelling of landslide remedial constructions’ behavior in physical models of scaled landslides in static (rainfall triggered landslides) and seismic conditions (earthquake triggered landslides). Static landslide triggering conditions will be reached by artificial rainfall using a rainfall simulator, while the seismic landslide triggering conditions will be induced by a pair of shaking platforms. Landslide movements will be observed with an innovative photogrammetric equipment and complex sensor network with ability to measure displacements, pore pressures and force pressures within a landslide body as well as at an applied remedial construction. Several different remediation constructions are planned to be embedded and their behavior tested in the small scale model: retaining walls, pile walls, buttressing and drainage systems. All measured data and results will be imported in 3D numerical model for stressstrain analysis. Results from both physical and numerical modelling will provide better insight into behavior of landslide remedial constructions in engineering practice. In this paper the development of the physical model platform will be described as well as some observations about conditions that should be reached during the small scale modelling research.
