以某复杂高层工程为例，采用灰色理论，系统研究了复杂高层箱筏基础沉降变形特性，结果表明沉降随建筑结构高程增加而增大，建筑完工后沉降基本趋稳，指出灰色理论能较好地反映复杂高层箱筏基础沉降变形预测，其预测沉降变形与实测较为吻合。%In this paper,taking a complex high-rise building project as an example,the application of gray theory,the system of complex tall building box raft foundation settlement deformation characteristics,the results show that settlement with the building height increases,the settle-ment after construction is completed the basic stabilization. Gray theory can reflect the deformation prediction of complex tall building box raft foundation settlement,the settlement deformation agree well with the measured.
