Firstly, short description of the problem and “state of the art” review are included. An effective methodology of the design supported by the numerical analysis, solving the problem of interaction of a periodic system of piles and the unstable soil mass is presented, for which some detailed information about proposed numerical approach is given. The key idea of 2D/3D method is to join the pile with the 2D plane strain continuum by fictitious connectors of Winkler type with P-Y properties identified during the analysis of a subsidiary 3D problem. Practical example of usage of proposed approach to a real case of a road endangered by a landslide then protected by the piles system is presented. On the base of this example, a discussion about important design issues like internal forces in piles (mainly bending moments) and anchors (tensile forces) or overall stability of the soil-structure system is done.}, type={Article}, title={Piles system securing road against landslide. 2D/3D method of numerical modeling and design problems}, URL={http://czasopisma.pan.pl/Content/118356/PDF/19a_D1433-1442_01648_Bpast.No.68-6_29.12.20_OK.pdf}, doi={10.24425/bpasts.2020.135378}, keywords={landslide, numerical analysis, piles, soil-structure interaction, multi-scale analysis}, }
