将高压架空输电线简化为悬索模型，对输电线的张力进行了研究，由于求解方程非线性，不能直观得到张力与悬线跨度、高差等变量的关系，故通过 MATLAB 软件进行求解。文中对冰厚与输电塔之间悬线高差的关系进行了研究，发现增加悬线的高差可以有效地提高输电线承受冰载的能力，从而为增强输电线的抗冰能力提供了新思路。

The transmission line was simplified as the cable model and the tension of transmission line was studied. Considering the nonlinearity of solving equations,the MATLAB software was used to get the relationship among line’s tension,span and height difference. Through researching about the relationship between the change of ice thickness and height difference,we find that increasing height difference can improve the ability of transmission lines under ice load efficiently,thus providing a new way to enhance the capacity of transmission line.
