摘要
随着输电线路输送容量及电压等级的不断提高,杆塔荷载及塔重不断增加,基础承担的偏心荷载大幅提高,传统基础型式未能充分考虑基础实际受力特征。本文通过三维有限元模型仿真分析,研究直柱不同偏心率下大板的基底位移和基底反力,得出最优偏心率,为工程设计提供依据。
The tower loads and tower weight increasing with the continuous improvement of transport capacity and voltage level of transmission lines, the eccentric load increased substantially which assumed on the basis. The traditional foundation type failed to fully consider the actual force characteristics of the basis. This paper studied the base displacement and base reaction force in different eccentricity, and got the optimal eccentricity through three dimensional ifnite model analyzing. The results provide the basis for engineering design.
