The influence of jute fiber and polyvinyl alcohol on the solidified silt was analyzed through the unconfined compressive strength test. The results showed that the addition of jute fiber and polyvinyl alcohol could not only improve the strength of the solidified silt, but also significantly improve the residual strength of the solidified soil. With the addition of fiber, the compressive strength of solidified soil increases first and then decreases with the increase of fiber content, and the optimal fiber content is 0.3%. The addition of PVA makes the compressive strength of solidified soil increase with the increase of fiber, and when the PVA content is 0.8%, the strength of solidified soil increases most obviously. Under the action of composite curing agent, the strength of solidified soil increases rapidly in the 1d-7d age, but decreases slowly in the 7d-14d age.
