针对分裂导线一间隔棒体系的覆冰脱落问题，建立了该体系的有限元模型。分析了分裂导线与合成单导线的覆冰脱落的差异以及分裂导线和间隔棒数量不同时的单根子导线脱冰时的响应。结果表明，如果要将n分裂导线的覆冰脱落问题用合成单导线来等效，则合成单导线的直径和覆冰厚度均要扩大√＂倍；脱冰档内的响应最大值一般位于最靠近跨中的位置；通常用来抑制导线舞动的间隔棒布置方法和布置间距的建议，在抑制由脱冰引起的间隔棒扭转问题上也有较好效果。

In allusion to ice-shedding of bundled conductor-spacers system, a finite element model of this system is built. The difference between ice-shedding of bundled conductor and that of single composite conductor as well as the response of bundled conductor and that of single sub-conductor with different number of spacers during ice-shedding are analyzed. Analysis results show that if the ice-shedding of n-bundle conductor is equivalent to that of single composite conductor, both diameter and thickness of ice-coating of single composite conductor should be multiplied by xfn; the maximum response of the span where ice-shedding occurs is located at the position that is generally most near the midspan; the suggestions on configuration of spacers to suppress conductor galloping and that on the layout of the spacing will play an effective role in restraining spacer torsion caused by ice-shedding.
