ABSTRACT
In preparation for the 2014 Winter Olympics in Sochi, a new road that combine highway with railway was constructed between Adler and Krasnaya Polyana. The combined road further goes on to the Alpika-Servis train station. It passes the valley of the river Mzymta. It is one of the most important objects in transportation infrastructure for the 2014 Olympics in Sochi. Olympic structures such as ski jumps, alpine skiing tracks and etc. are situated in the mountainous part of Sochi. The goal of our study was to identify monitoring technologies and criteria for landslide hazard assessment for effective early-warning monitoring of the combined road. The aim of this monitoring system is to support the transportation safety for the 2014 Olympics in Sochi. The results of the research have shown that as primary monitoring instrumentations should be used horizontal extensometers and inclinometers. They provide the highest accuracy of landslide deformation measurements. The criteria for landslide hazard assessment were developed on basis of 2010-2013 monitoring results. Mechanisms of landslides in the region have also been taken into account.
