At Hanoi city in Vietnam, the subway system will be planned for the purpose of modernizing a city's transportation network. In this study, a series of Oedometer tests and Consolidated - Undrained triaxial compression (CUB) tests were performed on Liquefied Stabilized Soil (LSS) based on Hanoi clay and LSS mixed with fibered material. The CUB test results of LSS based on Hanoi clay and NSF-CLAY were compared, and the influence of adding fibered material on effect of reinforcement were discussed. It was found that consolidation yield stress increases as increasing paper content and ductile property of LSS was improved by means of the effect of reinforcement on fibered material. Thus, It was found that the inhibiting effect of settlement increases.
