Basalt fiber is a new environmentally-friendly material with excellent potential for soil reinforcement in geotechnical engineering construction. This study explores the effects of freeze–thaw cycles on the unconfined compressive strength (UCS) and P-wave velocity (Vp) of lime-stabilized basalt fiber-reinforced loess. Reinforced loess samples with different proportions of basalt fiber and lime were subjected to 0, 1, 5, and 10 freeze–thaw cycles, and their UCS and Vp were subsequently measured. The test results showed that the addition of basalt fiber and lime to loess could enhance strength and improve resistance against freeze–thaw damage, and the freeze–thaw damage of reinforced loess decreases with the increase of basalt fiber content and length. A relationship between UCS and Vp of the reinforced samples was obtained for the same number of freeze–thaw cycles, and this relationship exhibited linear characteristics. The fitting results indicate that the Vp can be used to estimate the UCS after freeze–thaw damage. The research results not only have important practical significance in the application of basalt fiber in geotechnical engineering but also provide a reference for the non-destructive testing of the strength of loess after freeze–thaw cycles.

“…study, the nearness degrees are comparatively large for the clay content and c of the soils from forestland and sloping farmland. This reflects the relatively high clay content in these soils, because the clay particles have strong interparticle bonds and aggregate as a result of their high surface area, colloidal size, and many chemical bonds (Horn and Fleige 2003;Cao et al 2020). The nearness degree between sand content and c was relatively high in orchard land, possibly because the coarser sand particles affect soil cohesion by inhibiting soil aggregation and separating finer soil particles (Khalilmoghadam et al 2009).…”

“…For a given water content, c increases as dry density increases, whereas u shows little change (Ni et al 2012). Soil texture is used mainly as a primary indicator of soil resistance to erosion and affects the soil shear strength and frictional forces in coarse-textured soils or cohesive forces in fine-textured soils (Knapen et al 2007;Khaboushan et al 2018;Cao et al 2020). Havaee et al (2015) concluded that the shear strength parameters (c and u) depend on the soil's gravel content and particle size distribution.…”
