【摘要】 就当前大型钢筋混凝土柱大多数都习惯用分段法吊装的现状，提出了采用单机开式约束绳系整体吊装大型钢筋混凝土柱的新方法，阐述了该方法的基本思路，并就单机开式约束绳系进行了数学力学分析，用比卡迭代算法解算了非线性方程组。更多还原

【Abstract】 This paper, conceming to the situation that most heavy reinforced concrete columns are usually hoisted in different steps, advances a new methed to hoist the whole heavy reinforced concrete columns by adopting single crane -open restrained systems of a rope and pulleys, deals with the fundmental thought of this new methed, makes mathematical and mechanical analysis of single crane -open restrained systems of a rope and pulleys, and solves the non linear equations by picard iteration.更多还原
