摘　　要：根据变截面钢筋混凝土长柱吊装的实际工程需要，进行了双机三点吊吊装方案的研究分析，建立了双机二点吊吊装方案的数学模型，编制了微机软件。In order to meet the field demand of reinforced concrete long post hoisting, a study on the hoisting procedure is made for double-hoist three-point lifting, and a mathematical model for the double-hoist three-point lifting is established. Software is developed to solve problems encountered in the double-hoist three-point lifting.
