| 摘 要： | 长久以来，钢筋混凝土长柱吊装，其“最佳”约束位置（吊点）是以水平位置为危险态确定的，这在理论上及实践上均很不合理，其实，危险态并不在水平位置，而在某个旋转极值方位，本文主要阐述了旋转极值方位如何确定；最佳约束位置按什么原则确定及如何确定吊钩绳倾斜的影响等问题。

| Abstract: | This paper points out that the practice, in which the optimal re strained lifting points are located where the horizontal position is regarded as the dangerous state. Is unreasonable then, it discusses a method to determine the rotating extreme angle and the real optimum redtraiped lifting points. |
