摘　　要：通过分析广州老城区一大型深基坑工程引起的邻近建筑物沉降变形监测数据,研究了深基坑施工对邻近建筑物的影响,指出基坑变形控制设计的重点应从控制最终变形值转变为对施工全过程的动态变形控制;邻近建筑物沉降变形的大小随建筑物与基坑坑边距离的远近、建筑物的基础形式及坑内是否采取加固措施等而变化。The deformation monitoring results of the existing buildings are analyzed,with the construction of a deep foundation pit adjacent to existing buildings in Guangzhou as an example. Point out the key of deformation control is dynamic control of deformation. Deformation control should not only focus on the control of the final deformation value,but also focus on the deformation dynamic control of the whole construction process. The subsidence of existing building changes from the distance between existing building and foundation pit,foundation forms,and reinforcement technique for foundation pit.
