Обеспечение эксплуатационной надежности при проектировании автомобильных дорог в условиях Сибири и крайнего севера

Abstract

Complex natural and climatic, unfavorable soil-hydrogeological and cryogenic conditions of Siberia and the Far North require a special approach to the design of road structures. Taking into account the prediction of climate changes, the intensity and composition of traffic flow, a number of uncertainties arise at the design stage, which can lead to an unrealistic unaccounted picture during the operation of the highway. The article presents the criteria of operational reliability, the results of forecasting and changes in the operational characteristics of highways in the life cycle. It also provides the results of geo-radar surveys on the sections of operated highways, and concerns with the main provisions of ensuring operational reliability in the design of highways in Siberia in the II and III road-climatic zones. The results of the research give the recommendations for the conditions of the Far North. They are able to ensure operational reliability with a staged position requiring additional in-depth monitoring surveys.
