摘　　要：广商中心工程采用桩筏+承台基础,筏板厚度较大且变化较多,最大厚度达7.8m。为此,在超厚筏板中布置附加箍筋,将筏板面筋与底筋连为一体,提高筏板整体受力性能。由于巨型钢柱尺寸较大,因此采用埋入式柱脚,以保证结构安全。通过采用跳仓法施工、安装附加箍筋、预埋柱脚等关键施工技术,加快施工进度,保证筏板施工质量,达到良好施工效果。The foundation of pile raft and pile cap is adopted in Guangzhou Commercial Center project.The thickness of rafts is large and varied,and the maximum thickness is 7. 8 m. Therefore,additional stirrups are arranged in the super thick rafts to connect the surface reinforcement and bottom reinforcement,which can improve the overall mechanical performance of rafts. Due to the size of the huge steel columns is large,the embedded column base is adopted to ensure the structural safety. By adopting the key construction technologies such as sequence method construction,installation of additional stirrups and embedded column base,the construction progress is accelerated,the construction quality of rafts is guaranteed,and the good construction effect is achieved.
