On engineering-geological assessment of the hazard of rockfall phenomena

Abstract

The history of mountain road operation shows that rockfall phenomena are only rarely isolated episodes; usually they are periodically repeated and pose a constant threat to the normal operation of such roads. Identifying areas that pose a threat of rockfalls and fallouts and assessing the degree of their threat to the road is one of the primary tasks both in designing various measures to protect existing roads and in designing new ones. However, no objective and uniform methodology for assessing the threat of rockfall phenomena has yet been developed. This work is an attempt to provide an approximate methodology for assessing the degree of threat of rockfall phenomena to roads. Given the complexity of the issue under consideration and its novelty, this methodology cannot be considered fully developed, but it can already put an end to the existing inconsistency and provide an objective and uniform approach to this issue.
