Abstract

An integral tension test system for a large-tonnage basalt fiber anchor cable includes: a plurality of basalt fiber anchoring bars each comprising a basalt fiber reinforced plastic (BFRP) bundle, a steel strand, a first and a second steel casing pipes, the BFRP bundle including a plurality of BFRPs, and a grating array temperature, stress and vibration sensing optical cables bonded in the BFRP; a vibration table and a reaction frame arranged thereon, wherein the first steel casing pipe of the basalt fiber anchoring bar is located in the reaction frame, the steel strand penetrates one end of the reaction frame to be connected to a center hole jack, and the second steel casing pipe of each basalt fiber anchor cable is located outside the reaction frame to be anchored; and a data acquisition module connected to all of the grating array temperature, stress and vibration sensing optical cables.
