Abstract
The short fiber mixing reinforced soil method is a method of improving the mechanical properties of the ground by mixing short fibers into soil. Various things have been elucidated, such as the existence of the optimum value of the mixing ratio of the short fibers to the strength from the research which has been carried out so far. However, the reinforcement mechanism by mixing short fibers is not so clear. Also, the relationship between the mixing ratio and the reinforcing effect is often not clear in the setting conditions of the density of the test specimen. In this study, two kinds of test specimen preparation conditions were set, and then we carried out the triaxial compression tests using short fibers with different diameters in which mixing ratio were varied. From the result, the strength and deformation characteristics differed for each specimen preparation condition, and we considered about the reason.
