Abstract

The section near the village of Koumaria of the Egnatia Odos highway included a 300 m long cut and cover structure near the foot of a slope being undercut by a river. The combination of the temporary steep cut slopes and the unfavourable weather conditions with low field shear strengths led to successive slope failures in that area and resulted in a heavily affected profile. As a result the cut and cover structure was abandoned in favour of an open cut and various remedial measures were applied for the rehabilitation of the affected area. In the case of another 140 m long cut and cover of the highway near the village of Peristeri sliding movements took place during the excavation of the temporary cut slopes. Those were controlled using the observational method with a combination of earthworks, drainage and retaining measures which ensured the construction of the cut and cover structure.

Slope Stability Aspects of the Egnatia Odos Highway Project in Northern Greece

New York, New York

The section near the village of Koumaria of the Egnatia Odos highway included a 300 m long cut and cover structure near the foot of a slope being undercut by a river.
