Abstract: With the massive expansion of urban underground space development, foundation depth is increasing, underground anti-floating increasingly prominent.Anti-floating anchor rods are widely promoted because of their flexible layout, small stress on a single anchor, simple process and low cost. However, the traditional metal anti-floating anchors have poor corrosion resistance. Even with the use of casing pipes and anticorrosive measures, it is still impossible to avoid the influence of the stray current generated by the subway and other DC power supply systems on the corrosion of the steel anchors. Therefore, it is obviously difficult to guarantee the durability of using it as an underground permanent structure, so the anchor “time bomb” is said. In recent years, fiber reinforced polymer (FRP) has attracted more and more attention. Due to its high tensile strength, good insulation, and strong corrosion resistance, it is considered the best substitute for steel. At present, glass fiber reinforced polymer (GFRP) has been applied to many anchoring projects, while carbon fiber reinforced polymer (CFRP) is limited in its application in geotechnical engineering due to its high cost. The emergence of basalt fiber reinforced polymer (BFRP) materials provides new ideas for anti-floating underground structures. BFRP anchors are regarded as a good substitute for steel anchors due to their high tensile strength, strong corrosion resistance, and good dielectric pro-perties. This article first discusses the basic properties, mechanism and corrosion resistance of BFRP anchors, and then analyzes the reliability of BFRP anchors used in underground structure anti-floating engineering from indoor static anchoring, dynamic anchoring and field anchoring tests. Analyzing and demonstrating, and finally starting from economic benefits, according to the principle of equal strength, a comparative analysis of the cost performance of BFRP anchors is carried out, and new ideas are provided for the future development of BFRP anchors in the field of anti-floating engineering.
