ABSTRACT
An extensive landslide occured in the area of Malakasa, north of Athens, severing the traffic in the Athens – Thessaloniki highway and railway. An intensive programme of site investigation gave information about the nature of the landslide, the geological formations and the ground water level, helping the conception of the phenomenon. The existence of two samples from the slip surface of the landslide gave the opportunity to carry out thin-sample shear tests, while the subsequent slope stability analyses confirmed the results of the laboratory tests. Finally, the design of the remedial works, which are under construction now, is based on the results of the investigation and the analysis of the landslide, leading to the improvement of the stability of the landslide area.
