摘　　要：内悬浮外拉线抱杆组塔方式在输电线路施工中广泛使用,风荷载是户外施工环境中的主要影响因素,风力会引起吊装设备的晃动,增加拉索系统的负担,对施工人员和设备造成威胁。为了保证施工安全,对风载条件下内悬浮外拉线抱杆组塔吊装进行力学仿真分析是十分必要的。本文针对不同工况下的施工现场,运用有限元分析软件,对抱杆起吊过程中外拉线、承托绳和起吊绳张力进行分析,并与经验公式计算结果进行对比,确定经验计算公式适用情况,为内悬浮外拉线抱杆组塔施工前工器具选型、施工中实时监测数据提供参考。The inner suspension holding pole with outside pilling wires tower erection method is widely used in transmission line construction.In the outdoor construction environment,wind load is the main influencing factor.Wind load will cause the lifting equipment to shake,increase the burden on the cable system,and pose a threat to construction personnel and equipment.Therefore,it is necessary to conduct mechanical simulation analysis of the tower hoisting and erecting under wind load condition.In this paper,finite element analysis method is used to analyze the tension of the outside pilling wires,supporting wires and lifting wires during tower erection under different working conditions.The results are compared with the results calculated by the empirical formula,and the applicability of the empirical formula is defined.This study provides references for the selection of tools and equipment before the construction and realtime monitoring during construction.
