摘　　要：为提高平行钢绞线斜拉索成桥索力的精度和每股钢绞线所持索力的均匀性,从平行钢绞线斜拉索等值张拉法的基本理论出发,对现有的张拉力计算公式进行修正完善,提出更精确的张拉力计算公式,对单根钢绞线张拉力控制方法进行修正完善,提出了更精确的张拉力控制公式和控制方法。In order to improve the accuracy of the stay cable force, and improve the uniformity of the single steel strand cable force, the existing formula for calculating cable force was revised and perfected, and a more accurate formula for calculating cable force was presented. The existing control method of single steel strand cable force was also revised and perfected, and a more accurate control formula and control method for cable force was presented. These studies were conducted according to the basic theory of equal tensile force method of parallel strand stayed-cable.
