CONTROL OF FROST DEFORMATION OF SOIL ROADBEDS ON SIBERIAN RAILROADS

BOR'BA S MERZLOTNYMI DEFORMATSIIAMI ZEBLIANOGO POLOTNA NA ZHELEZNYKH DOROGAKH SIBIRI

Success in controlling frost deformations of the roadbed and an increase in the technical level of planning result in great degree from the extensive data received from geological engineering research. The latter must lead to a great differentiation of natural conditions corresponding to the regions. Special attention should be paid to the conditions and the nature of the freezing and secretion of the soils. The regions of deep seasonal freezing must be related to complex conditions. Planning, construction, and operation of the roadbed in such regions is based upon special requirements and norms which can be with practical experience. This report discusses the following topics: distribution and character of frost deformations on the roadbed; frost phenomena in the soil and their dependence on natural factors; the experience of the struggle to control heaving formations on West Siberian railroads; asbestos ballast as a mean of fighting frost deformation, and recommendations for applying anti-heave measures. Report notes that some drainages are incapable of preventing heave formations on new lines; asbestos ballast can be a means of controlling heaving; and grooves should not be used in the capacity of self-sufficient anti-heaving measures.
