Selection of concept of roads protection against avalanches
Abstract
The article dwells upon the conceptual design of antiavalanche protection of roads in highlands. The developed technologies allow to optimize protection against avalanches and avoid unjustified losses. Indeterminate-stochastic analysis is used. Relief, meteorological and seismic factors are taken into account. Weather databases are worked out for each avalanche site on each data. Besides, the relieves’ database is developed for zones of origin and transit. According to them, for all years there is calculated a degree of situation’s belonging to different levels of avalanche’s danger. The avalanche pressure on the road is calculated. Example of analysis is given.
