拉线结构通常用于支撑输电线路。它们通常具有轻质、安装容易、预组装和简单基础设计的优点。应用范围相当广泛，从简单的拉线木杆到非常大的拉线钢格构结构。本出版物描述了已使用的各种类型的拉线结构；展示典型的家伙和配件；说明锚和基础；探索拉线结构的分析和设计技术；讨论独特的施工和维护问题；并显示手动和计算机计算，以说明文档中讨论的一些概念。

Guyed structures are commonly used to support electric transmission lines. They generally have the advantage of lightweight, erection ease, pre-assembly, and simple foundation design. There is a considerable range of applications, from simple guyed wood poles to the very large guyed steel latticed structures.This publication describes the various types of guyed structures that have been used; presents typical guys and fittings; illustrates guy anchors and foundations; explores analysis and design techniques specific to guyed structures; discusses unique construction and maintenance problems; and displays both hand and computer calculations to illustrate some of the concepts discussed in the document.
