碩士 === 國立臺北科技大學 === 土木與防災研究所 === 102 === The classical one-dimensional consolidation theory for saturated soil has brought many successful applications in geotechnical engineering practice especially those related to consolidation settlement. The theory is not suitable for unsaturated soil application as the volume change of the soil mass and water volume are not considered. This study verifies the consolidation theory for unsaturated soil that was proposed by Fredlund and Hasan in 1979. Results from an analytical study and experimental test of one-dimensional consolidation test on unsaturated soil specimen were used for the verification study. Finally, the application of the unsaturated consolidation theory on a preloading consolidation case was also performed.
