Segregation potential from a highway embankment on thawed permafrost

摘要

Frost heave occurs in soils where there is seasonal soil freezing with a supply of water; and in the active layers of permafrost soils in cold regions. In a series of papers, Konrad and Morgenstern developed their theory for frost heave prediction using the concept of segregation potential (SP) in fine grained soils. Most research on segregation potential has been done in the laboratory under controlled laboratory conditions. Fewer projects have studied frost heaving of natural ground in the field. This paper presents estimates of segregation potential from data collected from an instrumented full-scale, relatively low, engineered embankment.
