介绍了双柱悬索拉线塔在国外的使用情况、悬索的找形及铁塔尺寸的确定方法。采用有限单元法分析了双柱悬索拉线塔的动力特性，结果表明:前16阶阵型为拉线振动；拉线及金具的受力较大，需要进一步研究新型金具。对双柱悬索拉线塔、自立铁塔、传统拉线塔的优缺点进行了对比，结果表明在占地不受控制时双柱悬索拉线塔的经济性明显。

This paper introduced the utilization of double column suspended guyed tower abroad, the form-finding of suspended cable and the size determination of tower. The dynamic characteristic of double column suspended guyed tower was analyzed using finite element method with guy vibration in first 16 dynamic models. The result shows that new type fittings need further studying due to the large stress of guy lines and fittings. The advantages and shortcomings of double column suspended guyed tower, self-supporting tower and traditional guyed tower were compared, and the results showed that double column suspended guyed tower was most economic when land occupation was not restricted.
