| Outline of Final Research Achievements |
In this study, effects of curing days, curing environment and slurry density on strength and deformation property of Liquefied Stabilized Soil (LSS) reinforced with fiber are discussed. A series of consolidated undrained triaxial compression test was performed on the specimens cured in laboratory and the specimens taken by block sampling at model ground constructed in the field. At the model ground, a series of portable Falling Weight Deflectometer (FWD) tests was curried out at curing days of 28, 56, 84 and 120 days, respectively. The validity to estimated the stiffness of LSS ground by using of a portable FWD is discussed. Based on the test results, the relationship between the EP.FWD and Etan was discussed. It is considered that the KP.FWD-value is able to estimate the stiffness of backfill ground constructed by LSS reinforced with fiber. And more, it is found that the high-quality backfill ground can be constructed by using of LSS reinforced with fiber compared to LSS.
