Landslides in the North Caucasus occur in rocks of different geological age and types. Landslide processes are attributed to the clay rocks of certain horizons - from loams of Quaternary age to shales of the middle Jura. The specific character of a landslide in clay rocks of different lithification degree is that as the surface layer is displaced a new sliding surface is formed. One of the landslides has destroyed oil-pipeline. The landslide massif is frontier, its length - 140-210m, width -320m, slope angle - up to 35°. To stabilise the landslide antilandslide measures have been developed and they include: 1) the supporting construction which presents a pile row (800mm in diameter) placed at the bottom side of the pipeline shelf; 2) original anchor constructions supporting surface hearths; 3) river anti-wash-out measures, involving overflow dam constructions of large stone and anchored brushwood bundles.
