摘要 In this study, in-situ testing results are given, and the analytical relationship of the vibrations' amplitudes inside an em- bankment by the thawing of the subgrade surface of seasonably deep frozen soils is provided. The peculiarities of the vi- bration waves' propagation during the springtime thawing of soils compared to those during the summertime period and the correlation of the vibrations with the under-rail basement moduln~ nf ala^tieitv nro dofinod In this study, in-situ testing results are given, and the analytical relationship of the vibrations' amplitudes inside an em- bankment by the thawing of the subgrade surface of seasonably deep frozen soils is provided.
