摘　　要：WQJX平行钢绞线拉索具有可实现单根钢绞线安装、张拉和更换的优点,结合重庆千厮门嘉陵江大桥WQJX15.2-139平行钢绞线拉索单根钢绞线换索演示实践,对WQJX平行钢绞线拉索单根换索工艺进行介绍。WQJX parallel stranded wire cables exhibit the advantage that single stranded wire can be installed, tensioned and replaced. In combination with demonstrative practice of replacement of single stranded wire in WQJX15 . 2-139 parallel stranded wire cables of Chongqing Qiansimen Jialing River Bridge, this paper introduces technique for single replacement of WQJX parallel stranded wire cables.

关 键 词：WQJX平行钢绞线拉索 单根换索 施工工艺
