摘　　要：直埋光缆线路防雷线是直埋光缆线路工程重要的一项设计要素,但通信线路工程设计规范中给出的设计要求比较模糊,实施困难。针对这个问题,本文首先根据光缆故障频度,分析光缆结构选型,然后结合通信线路工程设计规范要求和预算定额中的材料,分析设置在不同净距下不同材料情况的防雷线是否符合规范要求,最后给出直埋光缆线路防雷线设计建议。Lightning protection line is an important design element of direct buried optical cable line engineering,but the design requirements given in the design code of communication line engineering are fuzzy and diffi cult to implement.To solve this problem,firstly,the optical cable structure selection is analyzed according to the frequency of optical cable failure,and then the materials in the communication line engineering design specifi cation and budget quota are analyzed to determine whether the lightning protection lines with diff erent materials at diff erent clear distances meet the specifi cation requirements.Finally,given directly buried optical cable lines the design suggestions for lightning protection lines.
