| Research Abstract |
In this study, the strength and deformation characteristics of liquefied stabilized soil (LSS) reinforced by fiber material prepared in a ground were investigated. A series of Consolidated Undrained triaxial compression tests under the various conditions such as constant strain rate, constant deviator stress, changing strain rate during monotonic loading have been carried out for LSS reinforced with different fiber content at curing days of 28 and 56 days, respectively. Based on test results, it was found that the effect of time-dependency on strength and deformation properties of LSS reinforced by fiber material is small independent of amount of fiber material and the stiffness under loading of LSS reinforced by fiber material increases after applying a rate change or a creep in stress - strain curve before peak. Aseismic performance in ground is improved and toughness ground will be constructed when the Liquefied Stabilized Soil with fibered material is applied as backfilling.
