Measurement for Permeability of Frozen Soil by Transient Pulse Method

Abstract

In this study, permeability coefficient of frozen soil has been measured by transient pulse method for specimens in which ice lenses did not exist by applying axis stress more than ice pressure calculated by generalized Clausius–Clapeyron equation. The applicability of the transient pulse method for frozen soil was examined by comparing the previous study conducted by authors. It is found that the permeability coefficient has a dependency on temperature and changes drastically over the tested temperature range. These tendencies of the permeability coefficient under negative temperature were similar to the permeability coefficient obtained by the constant head permeability test. Therefore, it is concluded that transient pulse method can be available to measure the permeability coefficient of frozen soil.
