Landslide Stabilization in Building Practice: Methodology and Case Study from Autonomic Republic of Crimea

Within the framework of the IPL Project No 153 “Landslide protection structures and their development in the Autonomous Republic of the Crimea, Ukraine (ARCU)” the information about landslide protection structures and measures, prospects of their development in the ARCU was collected and structured; the target data base was created. In specific Crimean conditions driven piles are not used, as a rule, due to general spread of soils with high content of rock and hard rock inclusions presented by argillites and siltstones with sandstone layers. Bored piles have been widely used since 1968 on the Crimean landslide slopes. They allow successful fixation of landslides with the thickness of 15–20 m. One of the most efficient solutions for landslide protection is the retaining constructions based on the short underground piles (SUP). They are shortened bored piles, immersed below the slide surface on the calculated value and output above it at a distance providing overlapping of slipping soils. In the process of experimental work there appeared the need to choose the optimal testing mode. In summary, the above results of IPL Project No 153 were used for design structure No 1 in Gurzuf town and landslide protection structures No 2 in Koreiz town of landslide protection structures based on SUP’s technology. The seismicity of the construction sites is 8 points due to Medvedev–Sponheuer–Karnik seismic scale (MSK-64). At present all the building structures are commissioned in ARCU.
