在几种典型的气象下，分别对两种结构不同的自承式架空光缆进行了力学性能分析。在大跨距条件下用悬链法计算了光缆的相对伸长量与增强层厚度的关系曲线。其结果对架空光缆的优化设计与生产有重要的指导意义。
Under several typical weather conditions, the mechanical properties of two self-supported overhead cables with different structures were analyzed respectively. The relationship between the relative elongation of the cable and the thickness of the reinforced layer was calculated by the catenary method under the conditions of long span. The results of the overhead optical cable design and production of an important guide.
