It is shown that, the frost-heaving ratio of the gravel soil decreases after the first increase with the increase of the compaction degree, with its maximum at the compaction degree of 95% under the closed condition and with the same initial moisture content, and it increases linearly with the increase of the initial moisture content under the closed condition and with the same compaction degree. There are highly related functional relationship between the compaction degree, the initial moisture content and the frost-heaving ratio, which can be used to forecast related indicators in some cases. The frost-heaving ratio increases over several times under the open condition than under the closed condition. It is necessary to reduce the underground water level, to set the water-resisting layer, and to strictly control the compaction degree and the initial moisture content for the effective prevention and control of the soil frost., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=9nZzG0fJ0GMJDq9nqBZbYQ==, pdfFileSize=3223941, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
