| Summary: | As a reusable resource, remolded soils are often not utilized on a large scale due to their high water content and low bearing capacity. By using polyvinyl alcohol fiber (PVA) as reinforcing material and cement as cementing material, the remolded soil was improved into a usable consolidated remolded soil, and the effects of different fiber content, fiber length modulus, and conservation age on the static and dynamic characteristics of the consolidated remolded soil were investigated by conducting triaxial consolidated undrained shear tests and dynamic triaxial tests on the consolidated remolded soil. The results show that the use of PVA fiber reinforced cement can effectively improve the shear strength and dynamic strength of the remolded soil and reduce the water content of the remolded soil; the best effect on the static strength of the remolded soil was achieved when 0.1% of PVA fibers with a length of 6 mm were incorporated into the specimens at a conservation age of 28 d; the best effect on the dynamic strength of the remolded soil was achieved when 0.3% of PVA fibers with a length of 12 mm were incorporated into the specimens at a conservation age of 7 d. |
