摘　　要：为了在线路覆冰时期获得导地线的覆冰厚度,本文根据导地线的力学基本方程,研究了基于弧垂的导地线覆冰厚度的计算方法,得到了单一档、连续档条件下准确的计算导地线等值覆冰厚度的方法,并编制了计算机软件。验证计算表明,该方法能够准确获得导地线的等值覆冰厚度。In order to obtain the ice thickness covered the conductor and ground wire during the icing period,this paper proposes the arithmetic theory of ice thickness of the conduct and ground wire based on sag measuring,which is based on the basic force equation of the conduct.The calculating methods of the ice thickness in different condition,such as single span and continuous spans,are obtained.The calculation software has been developed.The engineering practice verification demonstrated that this method can accurately obtain the ice thickness of the conduct and ground wire.
