摘　　要：以上海董家渡金融城工程项目大体积地下室底板施工为例,利用有限元方法对比分析在不同施工工况中,设置后浇带和施工缝2种施工方案的基础底板沉降变形及结构应力。结果表明:取消主楼与主楼之间的沉降后浇带是完全可行的,避免了设置沉降后浇带可能引起的各种施工问题。Taking the construction of large-scale basement floor of Shanghai Dongjiadu financial city project as an example, the finite element method is used to analyze the settlement deformation and stress of foundation floor of two kinds of construction schemes: setting post-cast band or construction joint in different construction conditions. The results show that it is feasible to abolish the settlement post-cast band between the neighboring main buildings, which can avoid various construction problems caused by setting settlement post-cast band.
