Method for manufacturing and marking high-precision reference cable strand for main cable of suspension bridge
The invention relates to a method for manufacturing and marking a high-precision reference strand for a main cable of a suspension bridge, which comprises the following steps of: (1) marking the length of a standard wire, measuring the length and rechecking, and enabling the manufacturing precision of the standard wire to reach 1/30000; (2) a plurality of standard wires are arranged in the reference cable strand, the same mark points on the standard wires are mutually corrected, the post tension of the wires in the cable strand is dynamically adjusted according to the correction result, the in-strand error of the cable strand is reduced, and the length precision of the cable strand is improved; meanwhile, in consideration of the influence of intra-strand errors on the length of the cable strand, for the mark points of the main cable strand, the middle average value of the same mark points on the standard wires is taken, the position correction of the mark points is achieved, and the influence of the intra-strand errors on the length precision of the cable strand is reduced. And the marking error and the length error can be reduced by 1/2. And (3) arranging a plurality of reference cable strands.
本发明涉及一种悬索桥主缆用高精度基准索股制作及标记方法，包括：(一)、标准丝的长度标记和测长复核，标准丝制造精度达到1/30000。(二)、在基准索股内设置多根标准丝，通过对多根标准丝上的相同标记点互相校对，根据校对结果，动态调整索股内丝材的后张力，达到降低索股的股内误差，提高索股长度精度；同时考虑到股内误差对于索股长度的影响，对于主缆索股的标记点，取所设置的多根标准丝上相同标记点的中间平均值，实现对标记点的位置修正，减低股内误差对于索股长度精度的影响。标记误差和长度误差可降低1/2。(三)、设置多根基准索股。
