Ice Segregation and Frost Heaving

摘要

Major engineering projects have focused attention on problems created by the freezing of water in earth materials. The problems arise from the tendency of ice to form in lenses segregated from the surrounding soil. As these lenses grow, they are capable of generating large pressures that disturb the surface of the ground. The term frost heaving is used to describe this phenomenon. The report summarizes the current state of knowledge and areas of controversy or uncertainty that additional research might resolve.
