Abstract
The purpose of this study is to clarify the shear properties of short-fiber reinforced soil after freezing and thawing. Compaction tests were conducted on soil samples with three different short-fiber mixing ratios of 0, 0.1, and 0.3 %, and the maximum dry density decreased as the mixing ratio increased, and the optimum moisture content was almost the same regardless of the short-fiber mixing ratio. Ice lenses were observed in the specimens during the freezing process using a direct box shear test apparatus. Furthermore, the results of direct box shear tests using specimens compacted with various mixing ratios and subjected to freeze-thaw showed that the shear strength was maintained after freeze-thaw as the short-fiber mixing ratio increased.
