ABSTRACT
As a result of changes that occur at the land surface, deforestationand and flooding, in lately started to appear more often landslides. In the present article will present a landslide that affected a road in Botosani county from Romania and solutions were required to be taken to stop these unwanted phenomena. The landslide is carried out over a length of approximately 400 m, the first separation stage being at a distance of 5-10 m from the edge of the carriageway. The calculation of local and general stability of the slope was performed using GEO5 program. In order to land geotechnical prospecting were carried out surface and deep research through the implementation of two drillings in the dry system, cased, with a diameter of 140 mm, and two mechanical uncased drillings with a diameter of 60-36 mm. In order to strengthen the slope and eliminate its causes instability favors, the following consolidation works were designed: concrete retaining wall on large diameter bored piles, works to eliminate excess groundwater using siphon drains, concrete caissons, maintenance / repair of roads, canals collection of water on the left side of the road and systematization and vegetalizarea left side of the road..
