| 摘 要： | Ways of strengthening railway embankment basis on ice-rich permafrost are characterized by regulating cooling and warming factors for preservation of the basis in constantly frozen condition (with the help of snow removal, painting, sun-precipitation shed, cross-section cooling pipes, the film cover,and the longitudinal cooling device) or removing icy masses preventively from the basis and filling the cavities simultaneously with not subsiding soils (with use of jet geotechnology). Skilled-experimental development are shined on the basis of new ways of strengthening embankment basis on ice-rich frozen soils.
