Abstract: The basalt fiber is a green inorganic high-performance fiber, but the research on the basalt fibers in the soil improvement application is still in the preliminary stage. Based on the research progress domestic and overseas, the composition, types and special physical properties of the basalt fiber compared with traditional modifier are briefly introduced. This paper also summarizes the influence of the contents and methods of basalt fiber mix on the physical and mechanical properties of the soil mass. Further, the paper comprehensively considers the influence of durability, thermal conductivity after the mixing, explores the improvement of heavy metal contaminated ion soils by the basalt fiber, and integrates the mechanism of basalt fiber improvement on soil by using the potential of shallow geothermal energy, and to further explore the basalt fiber in various special properties.

Key words: basalt fiber, mixing ratio, mechanical properties, durability, thermal conductivity, improvement mechanism, review
