| Popis: |
The Bansko late antique thermal spa is located in the south-eastern part of the Republic of North Macedonia, ten kilometres southeast of the city of Strumitsa. The Bansko archaeological site covers an area of about 1500 m2, and the immediate vicinity of the site, which was the subject of research in terms of defining slope stability on its southwest side, covers an area of about 2 ha. Within the research of the exploration area, appropriate geological and geophysical researches were performed in order to define the slope stability. Geophysical seismic surveys are planned and performed in accordance with the geological conditions of the location, as well as the methodology of the combined seismic surveys. Seismic refractive and reflective surveys have been applied to define geomechanical parameters based on the fact that fragmented rock structures tend to absorb seismic energy which ultimately results in a reduction in registered seismic velocities. The seismic refraction method is applied in order to separate the surface earthen formations (based on the small values of the seismic propagation velocities) in the slope above the Roman bath which can be destabilised by further excavation and urbanisation of the area, while the method of reflection is applied for a more detailed limitation of the lime creations on the terrain, as well as for understanding the local tectonics that caused their occurrence. |
