摘 要: 通过大型有限元软件ANSYS8.0对桩基托换中主动托换顶升的模拟,建立顶升位移与上部结构内力的关系,从而确定顶升位移的大小,以便指导托换结构的设计与施工。 Elastic analysis of reinforced concrete frame during underpinning construction is carry out in the paper using finite element software-ANSYS. Find out the relationship of jack-displacement and the superstructure endogen force and determine the jack-displacement value. The results will provide the reference for the underpinning design and construction.
