Abstract
The results of a statistical analysis on landslide phenomena in Greece are presented here. The task is based upon 800 case-histories of landslide incidents, recorded up to 1986, retrieved from an original number of more than 1500 coded engineering reports and studies. The object concerns village areas and the road network. It especially refers to their frequency distribution and their consequences on different geological formations, altitudes, rain-fall, slope angles etc. Furthermore, assessments for the above parameters were made and certain interrelations were studied. Additionally an engineering geological map of Greece as well as landslide distribution and frequency zone maps were compiled on the basis of the evaluated data.
Résumé
Dans ce travail on présente une analyse statistique des phénomènes de glissements de terrain qui ont eu lieu dans les villages et sur le réseau routier du territoire grec, et qui sont enregistrés jusqu'en 1986. Ainsi, on a étudié et classifié 800 cas, décrits dans 1 500 rapports géotechniques. Spécialement, ont été étudiées la distribution et la fréquence de ces phénomènes et leurs relations avec les différentes formations géologiques, l'altitude, le niveau de pluie, les angles des pentes etc. Ces paramètres ont été évalués et des corrélations ont été établies. En plus, on a rédigé, à partir des données précédentes, la carte géotechnique de la Grèce, ainsi que les cartes de distribution et de zones de fréquence des glissements de terrain.
