Adding fiber into soil-cement can improve its compressive and tensile strength. In engineering application, soil-cement can meet the requirements of mechanical properties and economic cost by adding a certain proportion of fiber, which has great significance for ensuring engineering quality, and reducing cost and increasing efficiency. In order to reflect the strength characteristics of soil-cement mixed with fiber and the performance of fiber constrained lateral deformation, the unconfined compressive strength test of soil-cement with fiber was studied in this paper. The results show that the addition of fiber can improve the mechanical properties of soil-cement, reduce the development of cracks and improve the ductility of soil-cement. Under the condition of the same incorporation ratio, the compressive strength of basalt fiber to soil-cement is improved more than that of polypropylene fiber. The test results can provide technical support and practical reference for long-term engineering safety.
