摘要：

本文给出了长桩三点吊内力计算的几何法和解析法,发析了起吊高度、吊索长度、浸水等对内力的影响在最佳吊点计算中考虑了动力系数的影响,并分析了施工中吊索长度和吊点位置偏差对最大弯矩的影响。

The geometrical method and analytic method are given to calculate the internal forces of a long pile when it is being lifted from three points and the influence of lifting height, length of sling, submergence of pile, etc, upon the internal force of a pile is analyzed . The effect of dynamic factor is also taken in account when optimum lift points are being calculated. The influence of the length of sling and the location of lift points upon the maximum bending moment during handling operations is also analyzed.
