Intensive development of South Yakutia, a mountainous area in the Russian sporadic permafrost zone, must be founded on knowledge about regional permafrost conditions. New permafrost maps for mountainous areas in South Yakutia (the Elkon Mountains and the...

In this paper on the example of continuous spans of bridges the asymmetry influence of the scheme on the frequency and forms of natural oscillations is investigated. It is shown that under certain span lengths of regular schemes the use of them to determ...
