从平行钢绞线斜拉索张拉的基本原则出发，首先通过悬链线理论推导出拉索在目标状态下的索形方程和无应力索长计算公式；然后提出了平行钢绞线拉索张拉过程中的两类问题及求解这两类问题的数值计算方法，将其应用于求解平行钢绞线斜拉索单根索股的初张力；最后使用Matlab编制了计算程序，并以在建的铜陵公铁两用斜拉桥为工程背景进行算例分析，对算法的有效性进行验证。结果表明：文中提出的方法高效、可靠，可以为平行钢绞线斜拉索的施工提供理论参考。

Based on the basic stretch-draw principle of parallel strand stay cables,formulas respectively describing the configuration of target state and the unstressed cable length were set up according to the catenary theory.Then, two problems existing in the stretch-draw process of parallel strand stay cables were put forward,and the corre-sponding solving methods were proposed and a calculation program was compiled with Matlab to determine the sin-gle strand initial tension.Finally,a case study on the Tongling rail-road cable-stayed bridge under construction was conducted.The results show that the proposed method is effective and reliable,and that it may provide theoretical references for the construction of parallel strand stay cables.
