摘　　要：针对导线运动的小应变和小转角特点 ,结合间隔棒对导线的约束关系 ,推导建立了单元刚度矩阵。应用获得的公式体系对实际大跨越分裂导线进行了静力响应计算 ,提出了分裂导线的一种新型有限元模型 ,与实测结果比较 ,本文的方法和结果可靠。A new type of element for FEM procedure to solve the static response of the long span bundled multi-conductor structures is presented. Striffness matrix of the element is derived based on the differential equations of the conductor with small strain and small rotation, in which the constrained conditions imposed on the conductors by spacer are used. Numerical computations for a real power line structure are executed by using the element. The results are compared with the practical measured data, and it shows the method in this paper is reliable and effective.
