According to the topographical condition of Yangtze River large-crossing at Heiyanzi, two tension stringing styles of anti-twisting steel wire ropes with □15mm are adopted to cross Yangzi River by reasonably arranging tension field and pulling field. Pulling ropes are connected flexibly at strain tower according to the demands, and loop string of ropes in pulley wheels is applied to reduce transportation between tension field and pulling field, which are different from traditional ways and could raise working efficiency.
