Summary:
This thesis studies the landslide phenomena in the region K.P. 6+ 380 to K.P. 7
+750of the section 2.4 of Egnatia Odos. This region presents intense moving
activity, of about 10 mm / year, turning it into an area of intense scientific
interest.
The geological formations that make up the geological structure of the study
area, are the formations of flysch and ophiolites, where, according to the
studies, during the Alpine orogenesis the Olonos - Pindos zone moved to the
Ionian zone, and ophiolites were movedto the Pindos flysch. These intense
tectonic processes had a direct influence on the area’s rocks, thus developing
an important aquifer even in rocks considered practically impermeable
intensifying thus soil instabilities in the study area.
The main factors which influence the geotechnical conditions and favoring the
onset of landslide phenomena in the region, is the morphology of the relief,
the hydrographic network, the bedrock, climate conditions, hydrogeological
conditions and, of course, human activities.
All the above consist very important reasons for the study of the region,
through mathematical models which future may allow forecasting landslides in
the region, based on the above factors. Thus, an attempt was made, in this
thesis, to simulate the ground motion based on the rainfall data of recent
years in the area.
The analysis carried out, gave significant results with respect to the time of
a landslide may occur, which may, through the correct interpretation and
evaluation of results, help significantly, not only the local population, but
also the safe realization of major infrastructure projects in the study area.
In particular, through the comparison of the results of this study with those
of already known displacements in the region, it was found that there is a very
good match with the data recorded, which is very encouraging for the potential
future use of similar models for predicting landslide phenomena.
