摘要
输电线路杆塔整体组立施工设计的关键,是抱杆失效角及杆塔起吊角的确定．为此提出建立杆塔整体起吊抱杆失效时绳系约束方程和角度约束方程,给出两者之间的离散化的数学模型,采用VC++编程实现对模型的求解并实现可视化操作,研究符合实际施工需要的抱杆失效角及杆塔起吊角．
The determination of gin pole s failure angle and pole-tower's starting suspension angle is the key to transmission line pole-tower s starting construction design . In light of this ,a rope s hound equation and an angle s bound equation when the gin pole fails as the whole pole tower lifting are set up;and the discrimination mathematical mode between the two equations is given. Using VC++ programming ,a solutions to the model is given;and visual operation is attained;then the gin pole s failure angle and the pole tower s starting suspen-sion angle which both suit the need of actual construction are studied.
