This application relates to the field of suspension bridge cable strand processing technology, specifically disclosing a method for anchoring ultra-high strength cable strands. The method includes the following steps: collecting structural parameters of the anchor cup, wire separator, and wire bundle entities and constructing a digital twin model; collecting process parameters of the cable strand anchoring process and synchronously mapping them to the digital twin model; comparing the collected parameters with preset safety ranges, marking parameters that do not meet preset safety thresholds as process parameters to be adjusted; calculating the actual injection amount by collecting the alloy weight difference before and after anchoring; comparing the reverse displacement curve and injection amount of each anchor with historical qualified data intervals; if the range is exceeded, marking the anchor as a defective anchor and triggering an alarm; retrieving parameters of the defective anchor and analyzing them to obtain an optimized safety threshold range for the process parameters. The purpose of this patent is to solve the problem of lacking effective monitoring and control methods during the cable strand anchoring process, making real-time process monitoring and adjustment impossible.
