摘要
基于特高压输电线路内悬浮外拉线抱杆分解组塔施工的需求,提出了顶部拉线抱杆分解组塔施工的一个通用仿真力学模型,通过调整抱杆结构和工况参数,可适应内拉线或外拉线、内悬浮或固定卡脚等类别顶部打拉线抱杆分解组塔施工的精确计算;通过开发程序,可有效实现各种工况组塔施工的快速精确的力学分析和计算,进而优选工器具,优化吊装方案。
According to the requirements of UHV tower erection using guyed Liting pole, a general simulafed mechanical model is developed. By adjusting structural and working condition parameters of the Liting pole, the model can accommodate many situations, such as internal guyed or external guyed Liting pofe, and internal suspended or fixed Liting pole, etc. Fast and accurate mechanical analysis and calculation on all kinds of tower erections can be performed by the developed program, so that tools and hoisting schemes can be optimized.
