Purpose: to explore the territory of the alpine-climatic resort “Alpika-Service” in the North-Western Caucasus near the village of Esto-Sadok, Krasnopolyansky settlement district of Adler region of Sochi in field conditions for dangerous geological processes; on the basis of the conducted field survey of the territory, to determine the zones of mudflow accumulation, to assess the state of the existing mudflow protection structures; to make the necessary calculations of the mudflow in the program for designing flexible engineering protection systems DEBFLOW and to propose measures to stabilize the situation on this basis.
Methods and materials. In the course of research, the types of mudflow protection structures were described, it was determined that, according to climatic zoning, the site belongs to subarea III B1. The morphometric parameters of mudflows were determined by sampling and field surveys. On the basis of the DEBFLOW software, the calculation of the load on each designed barrier was carried out.
Results: three mudflow basins were found on the territory of the facility, which, during prolonged heavy rains and snowmelt, form mudflows causing damage to Olympic infrastructure facilities, including the Aibga-2 cable car and engineering protection facilities, a technological road, an antenna-mast building no. 2, a pedestrian crossing of the Alpika-Service alpine-climatic resort.
Conclusions. On the basis of field surveys, it was determined that the existing mudflow protection facilities are not enough to ensure the complete safety of the Olympic facilities and adjacent buildings. According to the calculations, the recommendations to stabilize the situation, namely along the Sulimovsky stream were given: installation of flexible mudflow protection barriers, placement of a network of catch drains and implementation of erosion-control measures.
