Abstract: Basalt fiber reinforced polymer (BFRP) tendons have the advantages of high tensile strength, strong resistance to alkali corrosion, good stability, and environmental protection. They have gradually become the best choice for nonmetal anchors. The field of soil anchoring is emerging. This article mainly introduces the research progress of BFRP anchors in terms of test, theory and numerical calculation, summarizes the types of anchor stress sensors needed to monitor the bolt pull-out test, and analyzes the existing FRP interface bond slip model and BFRP anchor factors affecting the bond strength of rods. In addition, related researches such as durability of BFRP anchors and numerical simulation analysis based on tests are introduced. Finally, the shortcomings of BFRP anchors are analyzed and discussed. Finally, recommendations are made for future developments in the anchoring field.

Key words: BFRP anchor, bond slip model, bond strength, durability, numerical simulation
