摘　　要：文章以华中地区某工业框架厂房功能性加固改造项目为例,分析了抽柱施工对原工业厂房结构框架梁、柱及地基基础的影响。通过抽柱后的框架梁、柱及地基基础的受力计算,提出增大截面法加固框架梁、柱及基地基础的改造方案。同时对增大截面法的施工流程及施工要点进行了梳理。Taking the functional reinforcement reconstruction project of an industrial frame plant in Central China as an example,this paper analyzes the influence of column extraction construction on the frame beam,column and foundation of the original industrial plant structure.Through the force calculation of the frame beam,column and foundation after column extraction,the reconstruction scheme of strengthening the frame beam,column and foundation by enlarged section method is proposed.At the same time,the construction process and key construction points of the enlarged section method are sorted out.
