(接上期)斜拉桥拉索制作与安装斜拉桥拉索主要采用高强钢丝索、钢绞线和其他刚性索。高强钢丝直径一般为5~7mm,以7mm更常见,标准抗拉强度为1570~1860MPa,根据设计要求布置每根索的钢丝数量,为方便索的盘整、运输,索内钢丝有适当扭角;钢绞线直径一般为12~15mm,一般情况下,每根钢绞线均有防护层。为降低风、雨振的影响,
(Continued) Cable-stayed bridge cable production and installation Cable-stayed bridge cable mainly adopts high-strength steel wire rope, strand and other rigid cable. High-strength steel wire diameter is generally 5 ~ 7mm, 7mm is more common, the standard tensile strength of 1570 ~ 1860MPa, according to the design requirements of the number of wires arranged per cable, for the convenience of cable consolidation, transportation, Strand diameter is generally 12 ~ 15mm, under normal circumstances, each strand has a protective layer. In order to reduce the impact of wind and rain,
