Integral tension test system for large-tonnage basalt fiber anchor cable and test method

An integral tension test system for a large-tonnage basalt fiber anchor cable, comprising:

• a plurality of basalt fiber anchoring bars, wherein each of the plurality of basalt fiber anchoring bars comprises a basalt fiber reinforced plastic (BFRP) bundle, a steel strand, a first steel casing pipe with two ends bonded to one end of the BFRP bundle and the steel strand respectively, and a second steel casing pipe bonded to the other end of the BFRP bundle, the BFRP bundle and the steel strand are centered in the first steel casing pipe, the BFRP bundle comprises a plurality of BFRPs which are bound and combined, and a grating array temperature sensing optical cable, a grating array stress sensing optical cable and a grating array vibration sensing optical cable are bonded in each of the BFRPs;
• a vibration table and a reaction frame arranged on the vibration table, wherein the reaction frame is of a closed structure, all the basalt fiber anchoring bars penetrate the reaction frame, the first steel casing pipe of each of the plurality of basalt fiber anchoring bars is located in the reaction frame, the steel strand penetrates one end of the reaction frame and a center hole jack, and the second steel casing pipe of each of the plurality of basalt fiber anchoring bars is located outside the reaction frame to be anchored;
• and
• a data acquisition module connected to all grating array temperature sensing optical cables, all grating array stress sensing optical cables and all grating array vibration sensing optical cables, so as to acquire temperature, stress and vibration of each of the BFRPs.
