| Outline of Final Research Achievements |
This research project has conducted the two main task: Improvement of mechanical model of fiber reinforced granular material, and Development of tensile creep test method considering soil environment. The study has clarified the deformation behavior of fibrous material in the granular material. The failure criterion of fiber reinforced granular material was proposed based on the deformation behavior of fibrous material. Moreover, the study has proposed the evaluation method of tensile force of fibrous material considering friction between fibrous material and granular material, and also the controlling method of soil temperature. The accelerated creep test under soil environment has become possible to conduct by evaluating the tensile force of fibrous material and by controlling soil temperature.
