摘要
利用ABAQUS有限元软件对桩基托换工程中托换大梁以及托换桩进行数值模拟,对浇筑后的结构进行建模,模拟工程结束后的状态,再对比千斤顶对原有结构及托换结构影响结果,分析托换前后的沉降位移变化特点。
Numerical sinmlation of underpinning girder and underpinning pile in pile foundation underpinning engineering was carried out by using ABAQUS finite element software. The structure after pouring was modeled, the state after the end of the sinmlation was sinmlated, and the structure and support of the jack were contrasted. Change the structure to affect the results and analyze the characteristics of the changes of set- flement before and after underpinning.
