Research Abstract

The engineering properties of saturated fine-grained soils are important to the design on soft grounds and to the effective utilization of sludge for construction. A hypothesis was proposed that the engineering properties of fine-grained soil might be interpreted from its behavior in a freezing process. Based on the test results, the following conclusions were obtained.(1)The permeability of fine-grained soils appears to be governed by the pore water expressed as a frozen void ratio rather than the total pore water.(2).The adsorbed water expressed as an unfrozen void ratio might be work as a part of the soils but has no influence over them.
