摘要
为研究索塔的受力特点,建立了平面杆系模型和空间模型,分析了3种塔形的优缺点,最终推荐采用倒Y形索塔方案,并分析了沉井不均匀沉降对其受力的影响。
In order to analyze the mechnical performance of cable bent tower, a plane beam-system and spatial model are established, three shapes of cable bent tower are compared.At last the Y-shape cable bent tower is choosed and the effect of differential settlement on its stress distribution is researched.
