摘      要：Ⅰ. ICE SEGREGATIONThe classical work of Tsytovich has concluded that an ice segregation and a frost heave in sandy gravel cannot occur during freezing in an open system. The authors got the same result at higher frost penetration rate. However, Chen found that there were a lot of ice crystals surrounding gravel containing silt-clay con-
