In order to investigate the mechanical properties of the basalt fiber-reinforced cemented soil subjected to the action of salt (Na₂SO₄) and drying-wetting cycles, a certain amount of fiber was added into the cemented soil. The specimens were soaked in different concentrations of salt solution, and then placed into an oven for drying subjected to a series of drying-wetting cycles. Based on the unconfined compressive strength tests, the characteristics of compressive strength under the curing condition of low and normal temperature were studied. And then, the effect of salt solution concentration and number of drying-wetting cycles on surface quality, compressive strength and stress-strain relationship of specimens were discussed. The results show that the curing condition of low temperature prevents the development of strength of cemented soil, however, basalt fiber can still improve the mechanical properties of cemented soil. The inclusion of fiber can effectively improve the resistance of cemented soil to the combined effect of salt solution and drying-wetting cycles, postpone the propagation of cracks on the surface of cemented soil, reduce the strength loss rate, and improve the residual strength. Results also indicate that there is an obvious peak in the testing curve.
