摘　　要：在输电线路中,塔线体系的安全运行是非常重要的。因此,可以利用Ansys分析软件对输电线路塔线体系进行模型的建立与分析。在分析过程中建立梁、桁架混合单元耦合模型,由理论计算得到的导地线自重荷载、风荷载、冰荷载,分别对塔线体系、单独地线模型进行动力学分析,得到塔线体系及单独地线自振频率,将之前学者分析的结果作为依据,以此验证分析结果的准确性。将Ansys软件计算的结果对比分析,得出两种情况下应力最大节点的位移历程变形图。In the transmission lines, the safety operation of the tower-line system is very important, Therefore, the ANSYS analysis software can be used to establish and analysis the tower-line system of the transmission lines. In the process of analysis, the model of the beam-truss hybrid element-coupled is build, the ground gravity load, wind load and ice load can be calculated by theoretical calculation, and the tower-line system model and separated ground model are respectively analyzed for dynamic, and get the natural frequency of vibration with the tower-line system mad the separated ground. Based on the result which is analyzed by the scholars,in order to verify the accuracy of the analysis in this paper. To make the calculated result contrast analysis by Ansys, and get the deformation of the maximum stress node displacement process about the both cases.
