Remains of Gediminas Castle hill (Vilnius, Lithuania): 3D numerical model behaviour

Abstract

This manuscript represents a historical influence of Gediminas Hill constructions and buildings for nowadays condition. According to latest investigations realized in 2019–2020 and obtained results, it was prepared three-dimensional numerical model. In this model it is included Gediminas Hill geological profiles with geotechnical parameters and Gediminas Castle remains (including pedestrian path, tunnels, funicular, etc.). Due to a very large computational resources necessity simulations realized in a private Vilnius Gediminas Technical University cloud. Created numerical model allows to simulate nowadays problems, mainly – slope stability. Gediminas Hill slope stability is lowest at the slope surfaces, where is the thickest technogenic soil layers. According to the shape and size of possible landslides formations, landslides assigned to shallow local landslides. Updated in-situ investigation results are used in the numerical model and it allows to simulate various environmental conditions which are affecting slopes stability and, in some case, can make influence for Gediminas Castel remains.
