抱杆多点整体扳立大型输电杆塔分析计算的Picard迭代法

Hoist of Large-Sized Pole or Tower Computed by Picard Iteration

在某些特殊情况下，跨江大型输电铁塔、钢筋混凝土输电杆塔，要用抱杆多点整体扳立方法立塔。本文首次用比卡（Ｐｉｃａｒｄ）迭代法解算了复杂复合约束绳系动点坐标的非线性方程组，该法具有极简单的特点。

In some special situations. the whole installation of a large-sized reinforced concrete pole or steel tower is completed by means of a support column and a complex restrained systems of a rope and pulleys. The complex stresses formulated by a non-linear equations set first may be solved by Picard interation to give satisfactory results.
