RELATIONSHIP BETWEEN FROST HEAVE PHENOMENA AND WATER MIGRATION IN COHESIVE SOILS UNDER CLOSED SYSTEM CONDITION

Abstract

In order to investigate the relationship between frost heave phenomena and water migration in cohesive soils, frost heave tests were performed on cohesive soils under closed system condition. In addition, it was also investigated the change in frost heave characteristics corresponding to the change in the prepared soil types.The main concluding remarks derived from these studies are as follows; i) Frost heave rates in consolidated specimens are greater than the corresponding values in compacted specimens at the early stage during frost. ii) The frost heave was also closely related with the water migration and that relationship was affected by the degree of saturation in the specimen. In addition, the change in frost heave characteristics corresponding to the change in the prepared soil types were compared and cleared.
