摘要
本文由三部分组成：第１部分概述了整体提升法的优缺，点和发展历史；第２部分探讨了由设计与施工共同确定整体提升施工方案的重要性和科学的研究方法，并给出了研究流程图；第３部分结合我国的升梁抬网法和升网滑模法两个典型工程的现场全过程跟踪实测，探讨了提升工艺如同步控制、升差对结构的影响、支座反力原始差值的影响等主要问题。
Abstract This paper consists of three parts. Inthe first part,the merits, demerits and the historyof the lift-up method are derribed briefly The arond part relates to the importance and the scientificprinciple of research on the lift-up method selecied by designere and constructors. Finally,in the caseof two typical construction works of lift up space grid struclure adopting the method of lift up beamsand the method of slide up forms,a whole process of pureuit measure at the site has been done,someprimary pmblems about the lift-up technique such as the synchronous lift-up control,the influenceof difference in lift-up on the structure and the initial difference in suppoit pressure have beenstudied.
